A prismatic surface is a surface generated by all the lines that are parallel geometry parallel to a given line geometry line and intersect a broken line that is not in the same plane geometry plane as the given line. The broken line is the directrix of the surface the parallel lines are its generators or elements . If the broken line is closed i.e. a closed polygon , then the surface is a closed prismatic surface . With regards to crystallography , a prismatic surface is a single face geometry face of a prismatic form, which is an open form consisting of three, four, or six identical faces related by a symmetry operator.

Technical date November 2010 In archaeology , a prismatic blade is a long, narrow, specialized lithic flake with parallel margins. Prismatic blades are removed from polyhedral blade lithic core core s through Pressure flaking pressure reduction . This process results in a very standardized finished tool and Debitage waste assemblage . While the prismatic blade industry is most often associated with obsidian especially in Pre Columbian Mesoamerica , it is not limited to that material chert , flint , and chalcedony blades are not uncommon. Morphology Image chunchucmil obsidian.jpg thumb An obsidian prismatic blade fragment from Chunchucmil , Yucat n , Mexico Prismatic blades are often trapezoid al in cross section see image , but very close in appearance to an isosceles trapezoid . Triangular blades in cross section are also common. The ventral surface of the prismatic blade is very smooth, sometimes bearing slight rippling reflecting the direction of applied force and a very small bulb of applied force indicative of pressure reduction . Flake scars are absent on the ventral surface of these blades, though Eraillure eraillure flakes are sometimes present on the bulb .

Bottom shows a sample piston cylinder cutout which utilizes a prismatic joint. A prismatic joint provides a linear sliding movement between two bodies, and is often called a slider, as in the slider crank linkage. A prismatic joint is formed with a polygonal cross section to resist rotation. See for example the dovetail joint and linear bearing linear bearings .

Every even perfect number is hexagonal, given by the formula math M p 2 p 1 M p ..., hence all known perfect numbers are hexagonal. For example, the 2nd hexagonal number is 2x3 6 the 4th ... as a sum of at most four hexagonal numbers is 130 number 130 . Adrien Marie Legendre proved in 1830 that any integer greater than 1791 can be expressed in this way. Hexagonal numbers can be rearranged into rectangular numbers of size n by 2 n &minus 1 . Hexagonal numbers should not be confused with centered hexagonal number s, which model the standard packaging of Wiener sausage s. To avoid ambiguity, hexagonal numbers are sometimes called cornered hexagonal numbers . Test for hexagonal numbers One can efficiently test whether a positive integer x is an hexagonal number by computing math n frac sqrt 8x 1 1 4 . math If n is an integer, then x is the n th hexagonal number. If n is not an integer, then x is not hexagonal. Other properties The italic n th number of the hexagonal sequence ... sum is taken to be 0.

Unreferenced date October 2007 Image HEXAGONALPHASE1.JPG thumb right Schematic of the molecular organisation in a type I hexagonal lyotropic liquid crystalline phase. A hexagonal phase of lyotropic liquid crystal is formed by some amphiphilic molecules when they are mixed with water or another polar solvent. In this phase the amphiphile molecules are aggregated into cylindrical structures of indefinite length and these cylindrical aggregates are disposed on a hexagonal lattice, giving the phase long range orientational order. In normal topology hexagonal phases, which are formed by type I amphiphiles , the hydrocarbon chains are contained within the cylindrical aggregates such that the polar apolar interface has a positive mean curvature . Inverse topology hexagonal phases have water within the cylindrical aggregates and the hydrocarbon chains fill the voids between the hexagonally packed cylinders. Normal topology hexagonal phases are denoted by H sub I sub while inverse topology hexagonal phases are deonted by H sub II sub . When viewed under a polarising microscope thin films of both normal and inverse topology hexagonal phases exhibit birefringence , giving rise to characteristic optical textures. Typically these textures are smoke like, fan like or mosaic in appearance. The phases are highly viscous and small air bubbles trapped within the preparation have highly distored shapes. gallery Image Hexagonal1a.jpg smokey optical texture of type I hexagonal phase Image Hexagonal2a.jpg mosaic optical texture of type I hexagonal phase Image Hexagonal3a.jpg mosaic focal conic optical texture of type I hexagonal phase gallery Category Liquid crystals ... more details

The resulting solid has 12 triangular face geometry faces , 8 vertex geometry vertices and 18 edges. The 12 faces are identical isosceles triangle s. It is one of an infinite set of bipyramid s. Having twelve faces, it is a type of dodecahedron , although that name is usually associated with the regular polyhedron regular polyhedral form with pentagonal faces. The term dodecadeltahedron is sometimes used to distinguish the bipyramid from the Platonic solid . The hexagonal bipyramid has a plane of symmetry which is Horizontal plane horizontal in the figure to the right where the bases of the two pyramids are joined. This plane is a regular hexagon . There are also six planes of symmetry crossing through the two apex geometry apices . These planes are rhombus rhombic and lie at 30 angle s to each other, perpendicular to the horizontal plane.
