Retroprismatorhombisnub hecatonicosachoron

The retroprismatorhombisnub hecatonicosachoron, or raprishi, is a scaliform polychoron. It consists of 120 small snub icosicosidodecahedra, 2400 triangular prisms combining into hexagrammic prisms, and 1440 pentagrammic cupolae. It can be formed by expanding the snub hecatonicosachoron to fit retrograde hexagrammic prisms between the seside cells and expanding the pentagrammic pyramids into pentagrammic cupolae. It is notable for having icosahedral snub polyhedra as cells.
