Small rhombated small stellated hecatonicosachoron

The small rhombated small stellated hecatonicosachoron, or sirsashi, is a nonconvex uniform polychoron that consists of 1200 triangular prisms, 120 icosidodecahedra, and 120 rhombidodecadodecahedra. 1 icosidodecahedron, 2 triangular prisms, and 2 rhombidodecadodecahedra join at each vertex. it can be obtained by cantellating the small stellated hecatonicosachoron.
