Bitruncated octaexon

The bitruncated octaexon, or bittoc, also called the bitruncated 7-simplex, is a convex uniform polyexon. It consists of 8 truncated heptapeta and 8 bitruncated heptapeta. 2 truncated heptapeta and 5 bitruncated heptapeta join at each vertex. As the name suggests, it is the bitruncation of the octaexon.
