Tetrakis (Paphlagonia)
Tetrakis ( grc, Τετράκις) was a ancient Greece, Greek town of ancient Paphlagonia on the Black Sea coast.''Periplus of Pseudo-Scylax'' Its site is unlocated but based on the position it occupies in the text of the ''Periplus of Pseudo-Scylax'', it would be west of Sinop, Turkey, Sinope. Its site is unlocated. References

Tetrakis Cuboctahedron
In geometry, the tetrakis cuboctahedron is a convex polyhedron with 32 triangular faces, 48 edges, and 18 vertices. It is a dual of the truncated rhombic dodecahedron. Its name comes from a topological construction from the cuboctahedron with the kis operator applied to the square faces. In this construction, all the vertices are assumed to be the same distance from the center, while in general octahedral symmetry can be maintain even with the 6 order-4 vertices at a different distance from the center as the other 12. Related polyhedra It can also be topologically constructed from the octahedron, dividing each triangular face into 4 triangles by adding mid-edge vertices (an ortho operation). From this construction, all 32 triangles will be equilateral. This polyhedron can be confused with a slightly smaller Catalan solid, the tetrakis hexahedron, which has only 24 triangles, 32 edges, and 14 vertices.

Tetrakis Square Tiling
In geometry, the tetrakis square tiling is a tiling of the Euclidean plane. It is a square tiling with each square divided into four isosceles right triangles from the center point, forming an infinite arrangement of lines. It can also be formed by subdividing each square of a grid into two triangles by a diagonal, with the diagonals alternating in direction, or by overlaying two square grids, one rotated by 45 degrees from the other and scaled by a factor of √2. Conway, Burgiel, and Goodman-Strauss call it a kisquadrille, represented by a kis operation that adds a center point and triangles to replace the faces of a square tiling (quadrille). It is also called the Union Jack lattice because of the resemblance to the UK flag of the triangles surrounding its degree-8 vertices. It is labeled V4.8.8 because each isosceles triangle face has two types of vertices: one with 4 triangles, and two with 8 triangles. As a dual uniform tiling It is the dual tessellation of the truncated ...

Tetrakis Legomenon
In corpus linguistics, a ''hapax legomenon'' ( also or ; ''hapax legomena''; sometimes abbreviated to ''hapax'', plural ''hapaxes'') is a word or an expression that occurs only once within a context: either in the written record of an entire language, in the works of an author, or in a single text. The term is sometimes incorrectly used to describe a word that occurs in just one of an author's works but more than once in that particular work. ''Hapax legomenon'' is a transliteration of Greek , meaning "being said once". The related terms ''dis legomenon'', ''tris legomenon'', and ''tetrakis legomenon'' respectively (, , ) refer to double, triple, or quadruple occurrences, but are far less commonly used. ''Hapax legomena'' are quite common, as predicted by Zipf's law, which states that the frequency of any word in a corpus is inversely proportional to its rank in the frequency table. For large corpora, about 40% to 60% of the words are ''hapax legomena'', and another 10% to 1 ...
