Rhombiprismic dishecatonicosachoron

The rhombiprismic dishecatonicosachoron, or rappady, is a nonconvex uniform polychoron that consists of 120 small rhombidodecahedra, 720 decagrammic prisms, and 120 quasitruncated dodecadodecahedra. One small rhombidodecahedron, two decagrammic prisms, and two quasitruncated dodecadodecahedra join at each vertex.

Its vertices are the same as those of its regiment colonel, the quasiprismatorhombated faceted hexacosichoron.
