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 <math>{\tilde{B}}_4</math> symmetry doubles on <math>{\tilde{D}}_4</math> in three possible ways, while <math>{\tilde{F}}_4</math> contains the highest symmetry.
