In six-dimensional geometry, a runcic 6-cube is a convex uniform 6-polytope. There are 2 unique runcic for the 6-cube.
Runcic 6-cube
Alternate names
- Cantellated 6-demicube
- Cantellated demihexeract
- Small rhombated hemihexeract (Acronym: sirhax) (Jonathan Bowers)
Cartesian coordinates
The Cartesian coordinates for the vertices of a runcic 6-cube centered at the origin are coordinate permutations:
(ñ1,ñ1,ñ1,ñ3,ñ3,ñ3)
with an odd number of plus signs.

This polytope is based on the 6-demicube, a part of a dimensional family of uniform polytopes called demihypercubes for being alternation of the hypercube family.
There are 47 uniform polytopes with D<sub>6</sub> symmetry, 31 are shared by the B<sub>6</sub> symmetry, and 16 are unique:
