Retrosphenoverted ditrigonal hexacosidishecatonicosachoron

The retrosphenoverted ditrigonal hexacosidishecatonicosachoron, or rawvid tixady, is a nonconvex uniform polychoron that consists of 600 regular octahedra, 120 truncated dodecahedra, and 120 small ditrigonal dodecicosidodecahedra. 1 octahedron, 2 truncated dodecahedra, and 2 small ditrigonal dodecicosidodecahedra join at each vertex.

It is in the same regiment as the sphenoverted hecatonicosidishexacosichoron.
