Small ditrigonary hexacosihecatonicositrishecatonicosachoron

The small ditrigonary hexacosihecatonicositrishecatonicosachoron, or sidtexhithi, is a nonconvex uniform polychoron that consists of 120 great icosidodecahedra, 600 octahedra, 120 great ditrigonal dodecicosidodecahedra, 120 icosidodecadodecahedra, and 120 small dodecicosahedra. Three great icosidodecahedra, three octahedra, six great ditrigonal dodecicosidodecahedra, six icosidodecadodecahedra, and six small dodecicosahedra join at each vertex.
