Demihepteractic honeycomb
- Demihepteractic honeycomb
The demihepteractic heptacomb is a uniform space-filling tessellation (or honeycomb) in Euclidean 7-space. It is constructed as an alternation of the regular hepteractic heptacomb.
It is composed of two different types of facets. The hepteracts become alternated into demihepteracts h{4,3,3,3,3,3} and the alternated vertices create heptacross {3,3,3,3,3,4} facets.
