There are 8 cantellation for the 6-orthoplex including truncations. Half of them are more easily constructed from the dual 6-cube

Construction There are two Coxeter groups associated with the cantellated 6-orthoplex, one with the B6 or [4,3,3,3,3] Coxeter group, and a lower symmetry with the D6 or [33,1,1] Coxeter group.

Coordinates Cartesian coordinates for the 480 vertices of a cantellated 6-orthoplex, centered at the origin, are all the sign and coordinate permutations of (2,1,1,0,0,0)
