Bitruncated heptapeton

The bitruncated heptapeton, also called the bitruncated 6-simplex, is a convex uniform polypeton. It consists of 7 hexatera and 7 bitruncated hexatera. 2 truncated hexatera and 4 bitruncated hexatera join at each vertex. As the name suggests, it is the bitruncation of the heptapeton.
