Small birhombated heptapeton

The small birhombated heptapeton or sabril, also called the bicantellated heptapeton or bicantellated 6-simplex, is a convex uniform polypeton. It consists of 7 small birhombidodecatera, 7 small rhombated hexatera, and 35 triangular-tetrahedral duoprisms. 3 small birhombidodecatera, 2 small rhombated hexatera, and 2 triangular-tetrahedral duoprisms join at each vertex. As the name suggests, it is the bicantellation of the heptapeton.
