Truncated octaexon

The truncated octaexon, or toc, also called the truncated 7-simplex, is a convex uniform polyexon. It consists of 8 regular heptapeta and 8 truncated heptapeta. 1 heptapeton and 6 truncated heptapeta join at each hexateric pyramidal vertex. As the name suggests, it is the truncation of the octaexon.
