Cantic 6-cube

In six-dimensional geometry, a cantic 6-cube (or a truncated 6-demicube) is a uniform 6-polytope.

Cartesian coordinates

The Cartesian coordinates for the 480 vertices of a cantic 6-cube centered at the origin and edge length 62 are coordinate permutations:

(±1,±1,±3,±3,±3,±3)

with an odd number of plus signs.
