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

Alternate names

• Truncated 6-demicube/demihexeract (Acronym thax) (Jonathan Bowers)^[1]

Cartesian coordinates

The Cartesian coordinates for the 480 vertices of a cantic 6-cube centered at the origin and edge length 6√2 are coordinate permutations:

(±1,±1,±3,±3,±3,±3)

with an odd number of plus signs.
