Retroinvertifrustary prismatotetrishecatonicosachoron

The retroinvertifrustary prismatotetrishecatonicosachoron, or rifupthi, is a nonconvex uniform polychoron that consists of 120 great dodecicosidodecahedra, 120 small icosicosidodecahedra, 120 small rhombidodecahedra, 120 icosidodecatruncated icosidodecahedra, and 1200 hexagonal prisms. Two great dodecicosidodecahedra, two small icosicosidodecahedra, two small rhombidodecahedra, 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.
