Properties Regular

In the geometry of hyperbolic 5-space, the 16-cell honeycomb honeycomb is one of five paracompact regular space-filling tessellations (or honeycombs). It is called paracompact because it has infinite vertex figures, with all vertices as ideal points at infinity. With Schläfli symbol {3,3,4,3,3}, it has three 16-cell honeycombs around each cell. It is self-dual.

Related honeycombs

It is related to the regular Euclidean 4-space 16-cell honeycomb, {3,3,4,3}.
