There are three main classes of regular polytope which occur in any number of dimensions: Simplices, including the equilateral triangle and the regular tetrahedron. Hypercubes or measure polytopes, including the square and the cube. Orthoplexes or cross polytopes, including the square and regular ... See more In elementary geometry, a polytope is a geometric object with flat sides (faces). Polytopes are the generalization of three-dimensional polyhedra to any number of dimensions. Polytopes may exist in any general number of … See more Nowadays, the term polytope is a broad term that covers a wide class of objects, and various definitions appear in the mathematical … See more Convex polytopes A polytope may be convex. The convex polytopes are the simplest kind of polytopes, and form … See more Every n-polytope has a dual structure, obtained by interchanging its vertices for facets, edges for ridges, and so on generally interchanging its (j − 1)-dimensional elements for (n − j)-dimensional elements (for j = 1 to n − 1), while retaining the … See more A polytope comprises elements of different dimensionality such as vertices, edges, faces, cells and so on. Terminology for these is not fully consistent across different authors. For example, some authors use face to refer to an (n − 1)-dimensional … See more Infinite polytopes Not all manifolds are finite. Where a polytope is understood as a tiling or decomposition of a … See more Polygons and polyhedra have been known since ancient times.
