In four-dimensional Euclidean geometry, the bitruncated 16-cell honeycomb (or runcicantic tesseractic honeycomb) is a uniform space-filling tessellation (or honeycomb) in Euclidean 4-space.

Symmetry constructions

There are 3 different symmetry constructions, all with 3-3 duopyramid vertex figures. The ${\tilde {B}}_{4}$ symmetry doubles on ${\tilde {D}}_{4}$ in three possible ways, while ${\tilde {F}}_{4}$ contains the highest symmetry.
