Retroprismatorhombiretrosnub hecatonicosachoron

The retroprismatorhombiretrosnub hecatonicosachoron, or raprarshi, is a scaliform polychoron. It consists of 120 small inverted retrosnub icosicosidodecahedra, 2400 triangular prisms combining into hexagrammic prisms, and 1440 pentagrammic cupolae. It can be formed by expanding the retrosnub hecatonicosachoron to fit hexagrammic prisms between the sirsid cells and expanding the pentagrammic pyramids into pentagrammic cupolae.

It is notable for having icosahedral snub polyhedra as cells.
