Small retrosphenoverted hecatonicosidishecatonicosachoron

The small retrosphenoverted hecatonicosidishecatonicosachoron, or srawv hidy, is a nonconvex uniform polychoron that consists of 120 dodecadodecahedra, 120 truncated icosahedra, and 120 icosidodecadodecahedra. 1 dodecadodecahedron, 2 truncated icosahedra, and 2 icosidodecadodecahedra join at each vertex.

It is in the same regiment as the small rhombated great hecatonicosachoron.
