Retrofrustary hexacosipentishecatonicosachoron

The retrofrustary hexacosipentishecatonicosachoron, or rafxophi, is a nonconvex uniform polychoron that consists of 120 dodecadodecahedra, 600 octahedra, 120 quasirhombicosidodecahedra, 120 great icosicosidodecahedra, 120 small rhombidodecahedra, and 120 small dodecicosahedra. One dodecadodecahedron, one octahedron, two quasirhombicosidodecahedra, two great icosicosidodecahedra, two small rhombidodecahedra, and two small dodecicosahedra join at each vertex.

Vertex coordinates
Its vertices are the same as those of its regiment colonel, the antifrustary hexacositrishecatonicosachoron.
