Demienneract

Demienneract

A demienneract or 9-demicube is a uniform 9-polytope, constructed from the 9-hypercube, enneract, with alternated vertices deleted. It is part of a dimensionally infinite family of uniform polytopes called demihypercubes.

Coxeter named this polytope as 161 from its Coxeter-Dynkin diagram, with a ring on one of the 1-length Coxeter-Dynkin diagram branches.
