High Quality Content by WIKIPEDIA articles! In five-dimensional geometry, a pentacross, also called a triacontakaiditeron, is a five-dimensional polytope with 10 vertices, 40 edges, 80 triangle faces, 80 octahedron cells, 32 5-cell hypercells. It is a part of an infinite family of polytopes, called cross-polytopes or orthoplexes. The dual polytope is the 5-hypercube or penteract. The name pentacross is derived from combining the family name cross polytope with pente for five (dimensions) in Greek.
