Prismatorhombisnub hecatonicosachoron

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