Retrofrustary prismatopentishecatonicosihexacosichoron

The retrofrustary prismatopentishecatonicosihexacosichoron, or rafpophix, is a nonconvex uniform polychoron that consists of 120 dodecadodecahedra, 600 octahedra, 120 quasirhombicosidodecahedra, 120 great dodecicosahedra, 120 small dodecicosidodecahedra, 120 icosidodecatruncated icosidodecahedra, and 1200 hexagonal prisms. One dodecadodecahedron, one octahedron, two quasirhombicosidodecahedra, two great dodecicosahedra, two small dodecicosidodecahedra, four icosidodecatruncated icosidodecahedra, and four hexagonal prisms join at each vertex.

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