Retroinvertifrustary prismatopentishecatonicosihexacosichoron

The retroinvertifrustary prismatopentishecatonicosihexacosichoron, or rifpophix, is a nonconvex uniform polychoron that consists of 120 dodecadodecahedra, 600 octahedra, 120 great rhombidodecahedra, 120 small icosicosidodecahedra, 120 small dodecicosidodecahedra, 120 icosidodecatruncated icosidodecahedra, and 1200 hexagonal prisms. One dodecadodecahedron, one octahedron, two great rhombidodecahedra, two small icosicosidodecahedra, 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.
