Birectified octaexon

The birectified octaexon, or broc, also called the birectified 7-simplex, is a convex uniform polyexon. It consists of 8 rectified heptapeta and 8 birectified heptapeta. 3 rectified heptapeta and 5 birectified heptapeta join at each triangular-pentachoric duoprismatic vertex. As the name suggests, it is the birectification of the octaexon.

It is also a convex segmentoexon, as a rectified heptapeton atop birectified heptapeton.
