Retrosphenoverted hexadecatesseractioctachoron

The retrosphenoverted hexadecatesseractioctachoron, or rawvhitto, is a nonconvex uniform polychoron that consists of 8 cuboctahedra, 8 truncated octahedra, and 16 octahemioctahedra. 1 cuboctahedron, 2 truncated octahedra, and 2 octahemioctahedra join at each vertex.

It is in the same regiment as the rectified icositetrachoron, although only having a third of its symmetry.
