A pentacross is a name for 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. The dual family is called the measure polytopes and the dual polytope can be called a penteract.
The name pentacross is derived from combining the family name cross polytope with pente for five (dimensions) in Greek.
[edit] Cartesian coordinates
Cartesian coordinates for the vertices of a pentacross, centered at the origin are
- (±1,0,0,0,0), (0,±1,0,0,0), (0,0,±1,0,0), (0,0,0,±1,0), (0,0,0,0,±1)
