In eight-dimensional geometry, a cantic 8-cube or truncated 8-demicube is a uniform 8-polytope, being a truncation of the 8-demicube.
Alternate names
- Truncated demiocteract
- Truncated hemiocteract (Jonathan Bowers)
Cartesian coordinates
The Cartesian coordinates for the vertices of a truncated 8-demicube centered at the origin and edge length 6√2 are coordinate permutations:
- (±1,±1,±3,±3,±3,±3,±3,±3)
with an odd number of plus signs.
