Bitruncated 16-cell honeycomb

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.
