Penteract

The penteract, or pent, also called the 5-cube, decateron, or square-cubic duoprism, is one of the 3 regular polytera. It has 10 tesseracts as facets, joining 5 to a vertex. It is the 5-dimensional hypercube.

It can be alternated into a demipenteract, which is uniform.

Vertex coordinates
The vertices of a penteract of edge length 1, centered at the origin, are given by:
