Small ditrigonary dishecatonicosidishexacosihecatonicosachoron

The small ditrigonary dishecatonicosidishexacosihecatonicosachoron, or sidtid hidixhi, is a nonconvex uniform polychoron that consists of 120 great icosidodecahedra, 600 octahedra, 120 small icosicosidodecahedra, 120 quasitruncated dodecadodecahedra, and 600 cubohemioctahedra. Three great icosidodecahedra, three octahedra, six small icosicosidodecahedra, twelve quasitruncated dodecadodecahedra, and six cubohemioctahedra join at each vertex.

Vertex coordinates
Its vertices are the same as those of its regiment colonel, the rectified small ditrigonary hexacosihecatonicosachoron.
