Small retrosphenoverted hecatonicosihexacosihecatonicosachoron

The small retrosphenoverted hecatonicosihexacosihecatonicosachoron, or srawv hixhi, is a nonconvex uniform polychoron that consists of 600 octahemioctahedra, 120 icosidodecahedra, and 120 truncated icosahedra. 1 icosidodecahedron, 2 truncated icosahedra, and 2 octahemioctahedra join at each vertex.

Vertex coordinates
Its vertices are the same as those of its regiment colonel, the small rhombated hexacosichoron.
