Octachlorodibenzodioxin (can be abbreviated as OCDD) is one of polychlorinated dibenzodioxins (PCDDs). Its toxicity is similar to TCDD, but it is about 3000 times weaker. It is one of the dominant dioxin congeners in smoke emissions, but because it is much less soluble than e.g. TCDD, it is not bioaccumulated as effectively and it is toxicologically less important than the most prevalent dioxins (for details see Dioxins and dioxin-like compounds).

Octahedrites are the most common structural class of iron meteorites. The structures occur because the meteoric iron has a certain nickel concentration that leads to the exsolution of kamacite out of taenite while cooling.

Octa (or Octha) (c. 500 – 543) was an Anglo-Saxon King of Kent during the 6th century. Sources disagree on his relationship to the other kings in his line; he may have been the son of Hengist or Oisc, and may have been the father of Oisc or Eormenric. The dates of his reign are unclear, but he may have ruled from 512 to 534 or from 516 to 540. Despite his shadowy recorded history Octa made an impact on the Britons, who describe his deeds in several sources.

Octaazacubane is a hypothetical explosive allotrope of nitrogen with formula N8, whose molecules have eight atoms arranged into a cube. (By comparison, nitrogen usually occurs as the diatomic molecule N2.) It can be regarded as a cubane-type cluster, where all eight corners are nitrogen atoms bonded along the edges. It is predicted to be a metastable molecule, in which despite the thermodynamic instability caused by bond strain, and the high energy of the N–N single bonds, the molecule remains kinetically stable for reasons of orbital symmetry.

In geometry, the octagrammic antiprism is one in an infinite set of nonconvex antiprisms formed by triangle sides and two regular star polygon caps, in this case two octagrams.

Octagon houses were a unique house style briefly popular in the 1850s in the United States and Canada. They are characterised by an octagonal (eight-sided) plan, and often feature a flat roof and a veranda all round. Their unusual shape and appearance, quite different from the ornate pitched-roof houses typical of the period, can generally be traced to the influence of one man, amateur architect and lifestyle pundit Orson Squire Fowler.

Octagon City is a ghost town in Allen County, Kansas, United States. It was a failed intentional community that was founded in 1856 about six miles (10 km) south of Humboldt, Kansas near the Neosho River. It was created by the Vegetarian Kansas Emigration Company, headed by prominent vegetarian Henry Clubb and entrepreneurs Charles DeWolfe and John McLaurin. The original intent was to build a vegetarian commune on the south side of the Neosho River for vegetarians only, but investor interest in a non-vegetarian moral community was much higher and so the decision was made to build Octagon City on the north side of the Neosho River to make the entire project sustainable. Members of Octagon City were under oath to educate their children and uphold a moral lifestyle.The city's design was influenced by Orson Squire Fowler, a leading advocate of octagon house architecture. Octagon City would feature an octagonal town square from which would radiate eight roads. Between the roads, in a four-square-mile area, sixty-four families would build octagonal farmhouses with octagonal barns.During May 1856, about 100 participating settlers arrived at the development site, expecting a blossoming town with grist mill and sawmill, but finding only one log cabin, one plow, and dozens of tents sheltering families. The site was very remote, and the nearest source of goods was in Fort Scott, Kansas, about 50 miles (80 km) away, so residents were forced to adapt and improvise. Mosquitoes, a flu-like epidemic ascribed to malnutrition, exhaustion, or malaria, the threat of Border Ruffians, and strong thunderstorms were a continuous problem. By early July the springs feeding the community had dried up. Some residents chose to live at an Osage Indian settlement a few miles away, which had a flowing spring, but they were forced to flee back to Octagon City upon learning that the tribe was about to return from its annual buffalo hunt. The summer months saw a continuous exodus of settlers and the population quickly thinned. By August, crop theft by Indians became a major problem.Very few of those remaining past summer had any intention of making permanent homes in Kansas. They waited only for opportunities to get away. By 1857 only four of the original residents were left, and the survivors reported more illness as the weather became warmer again.The area remained remote until 1873 with the arrival of the railroad. The town of Chanute, Kansas sprung up four miles (6 km) south of the former commune. Nothing survives of the settlement except the tributary Vegetarian Creek. A marker was erected near the site in 1986, but due to repeated vandalism it was removed in 2001 and donated to the St. Paul/Neosho County Museum.

The Octacube is a large, steel sculpture of a mathematical object: the 24-cell or "octacube". Because a real 24-cell is four-dimensional, the artwork is actually a projection into the three-dimensional world. Octacube has very high intrinsic symmetry, which matches features in chemistry (molecular symmetry) and physics (quantum field theory).The sculpture was designed by Adrian Ocneanu, a mathematics professor at Pennsylvania State University. The university's machine shop spent over a year completing the intricate metal-work. Octacube was funded by an alumna in memory of her husband, Kermit Anderson, who died in the September 11 attacks. The sculpture is displayed in the lobby of Penn State's math department.

The Octagon House is a historic octagon house at 21 Spring Street in Danbury, Connecticut, United States. It is considered the best octagon house of those that survive in Connecticut. In 1973 it was added to the National Register of Historic Places to avert its demolition in urban renewal.It is west of downtown Danbury in a residential area approximately midway along Spring between Beaver and New streets. The house itself is set back further from the street than its neighbors. It is a three-story building of one-foot–thick (30.5 cm) concrete walls faced in stucco. An octagonal cupola rises from the center of the almost flat roof, with two brick chimneys rising from the exterior walls at the southwest and southeast facets.Verandas with cast iron railings and supports run around the upper stories. The wide roof eaves, both on the main house and the cupola, have scroll brackets. The ornate ironwork of the verandas contrasts with the simple wooden door and window surrounds.The house was built in 1852 by Daniel Starr. He was following closely the precepts of octagon houses laid out by Orson Squire Fowler in his book A Home for All, all the way to the use of concrete as the main structural material. At the time of its construction Spring Street did not exist, so it fronted on Elm Street to the north. It has been well-maintained and preserved throughout its existence, even after its partition into apartments.

To put it algebraically, the n-th octagonal number is x n = n 2 + 4 ∑ k = 1 n − 1 k = 3 n 2 − 2 n . {\displaystyle x_{n}=n^{2}+4\sum _{k=1}^{n-1}k=3n^{2}-2n.} The octagonal number for n can also be calculated by adding the square of n to twice the (n - 1)th pronic number.Octagonal numbers consistently alternate parity.Octagonal numbers are occasionally referred to as "star numbers," though that term is more commonly used to refer to centered dodecagonal numbers.

In the geometry of hyperbolic 3-space, the octahedron-hexagonal tiling honeycomb is a paracompact uniform honeycomb, constructed from octahedron, hexagonal tiling, and trihexagonal tiling cells, in a rhombicuboctahedron vertex figure. It has a single-ring Coxeter diagram, , and is named by its two regular cells.A geometric honeycomb is a space-filling of polyhedral or higher-dimensional cells, so that there are no gaps. It is an example of the more general mathematical tiling or tessellation in any number of dimensions.Honeycombs are usually constructed in ordinary Euclidean ("flat") space, like the convex uniform honeycombs. They may also be constructed in non-Euclidean spaces, such as hyperbolic uniform honeycombs. Any finite uniform polytope can be projected to its circumsphere to form a uniform honeycomb in spherical space.

The Octagon House is a historic octagon house at 21 Spring Street in Danbury, Connecticut, United States. It is considered the best octagon house of those that survive in Connecticut. In 1973 it was added to the National Register of Historic Places to avert its demolition in urban renewal.It is west of downtown Danbury in a residential area approximately midway along Spring between Beaver and New streets. The house itself is set back further from the street than its neighbors.

In geometry, the octagonal antiprism is the 6th in an infinite set of antiprisms formed by an even-numbered sequence of triangle sides closed by two polygon caps.Antiprisms are similar to prisms except the bases are twisted relative to each other, and that the side faces are triangles, rather than quadrilaterals.In the case of a regular 8-sided base, one usually considers the case where its copy is twisted by an angle 180°/n. Extra regularity is obtained by the line connecting the base centers being perpendicular to the base planes, making it a right antiprism. As faces, it has the two n-gonal bases and, connecting those bases, 2n isosceles triangles.If faces are all regular, it is a semiregular polyhedron.

Octagon houses were a unique house style briefly popular in the 1850s in the United States and Canada. They are characterised by an octagonal (eight-sided) plan, and often feature a flat roof and a veranda all round. Their unusual shape and appearance, quite different from the ornate pitched-roof houses typical of the period, can generally be traced to the influence of one man, amateur architect and lifestyle pundit Orson Squire Fowler. Although there are other octagonal houses worldwide, the term octagon house usually refers specifically to octagonal houses built in North America during this period, and up to the early 1900s.

In astronomy, an octaeteris (plural: octaeterides) is the period of eight solar years after which the moon phase occurs on the same day of the year plus one or two days.This period is also in a very good synchronicity with five Venusian visibility cycles (the Venusian synodic period) and thirteen Venusian revolutions around the sun (Venusian sidereal period). This means, that if Venus is visible beside the moon, after eight years the two will be again close together near the same date of the calendar.The octaeteris, also known as oktaeteris, was noted by Cleostratus in ancient Greece as a 2923.5 day cycle. The 8 year short lunisolar cycle was probably known to many ancient cultures. The mathematical proportions of the octaeteris cycles were noted in Classic Vernal rock art in northeastern Utah by J. Q. Jacobs in 1990. The Three Kings panel also contains more accurate ratios, ratios related to other planets, and apparent astronomical symbolism.The octaeteris is the calendar used for the Olympic games, every four years and the Greek use 50 months of one Olympiad, four-year cycle and 49 lunarmonths for the next Olympiad. This octaeteris calendar exist in the Antikythera Mechanism and is used for the Olympic dial of this ancient automaton, to determine the time of the Olympic games and other Greek festivities.

Octaazacubane is a hypothetical explosive allotrope of nitrogen with formula N8, whose molecules have eight atoms arranged into a cube. (By comparison, nitrogen usually occurs as the diatomic molecule N2.) It can be regarded as a cubane-type cluster, where all eight corners are nitrogen atoms bonded along the edges.

Octadecene is a long-chain hydrocarbon and an alkene with the molecular formula C18H36. There are multiple structural isomers of octadecene, depending on the position of the double bond. 1-Octadecene, an alpha-olefin, is a relatively inexpensive solvent, with a boiling point of 315 °C. It is compatible with oleic acid.Octadecene is used in the synthesis of colloidal quantum dots, but it can possibly be replaced by heat transfer fluids such as Dowtherm A or Therminol 66 in this process.

In geometry, an octahedron (plural: octahedra) is a polyhedron with eight faces, twelve edges, and six vertices. The term is most commonly used to refer to the regular octahedron, a Platonic solid composed of eight equilateral triangles, four of which meet at each vertex.A regular octahedron is the dual polyhedron of a cube. It is a rectified tetrahedron. It is a square bipyramid in any of three orthogonal orientations. It is also a triangular antiprism in any of four orientations.An octahedron is the three-dimensional case of the more general concept of a cross polytope.A regular octahedron is a 3-ball in the Manhattan (ℓ1) metric.

The Octagon House was a historic house at 120 Strawberry Hill Avenue, on the edge of the Glenbrook section of Stamford, Connecticut. It was one of a number of octagon houses in the United States, built during a fad in buildings of that shape from the late 1840s to the 1870s. The octagonal portion of the house was concrete, with external scoring to imitate ashlar.

Octagoncito (born April 24, 1974) is a Mexican Luchador enmascarado, or masked professional wrestler, who works in the Mini-Estrellas ("Mini-Stars") division on the Mexican Independent circuit. He is the first wrestler to work as Octagoncito, with Asistencia Asesoría y Administración (AAA) giving the same ring character to a second Octagoncito when the original one left the promotion in 1995. Octagoncito's real name is not a matter of public record, as is often the case with masked wrestlers in Mexico where their private lives are kept a secret from the wrestling fans. In addition to working for AAA Octagoncito has also worked for Consejo Mundial de Lucha Libre (CMLL), Lucha Libre USA, World Wrestling Federation (WWE), World Championship Wrestling (WCW) New Japan Pro Wrestling (NJPW) and a slew of smaller wrestling promotions. Working in the Mini division does not necessarily mean that Octagoncito has dwarfism, as short wrestlers can also work in the "Mini" division.

The octadecanoid pathway is a reasonably well-characterized biosynthetic pathway for the production of the phytohormone jasmonic acid (JA), an important hormone for induction of defense genes. JA is synthesized from alpha-linolenic acid, which can be released from the plasma membrane by certain lipase enzymes. For example, in the wound defense response, phospholipase C will cause the release of alpha-linolenic acid for JA synthesis.In the first step, alpha-linolenic acid is oxidized by the enzyme lipoxygenase. This forms 13-hydroperoxylinolenic acid, which is then modified by a dehydrase and undergoes cyclization by allene oxide cyclase to form 12-oxo-phytodienoic acid. This undergoes reduction and three rounds of beta oxidation to form jasmonic acid.
