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