Prismatorhombiretrosnub hecatonicosachoron

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