Small ditrigonary hecatonicosihecatonicosihexacosidishecatonicosachoron

The small ditrigonary hecatonicosihecatonicosihexacosidishecatonicosachoron, or sidthihixady, is a nonconvex uniform polychoron that consists of 120 small ditrigonary icosidodecahedra, 120 great icosicosidodecahedra, 120 rhombidodecadodecahedra, 120 quasitruncated dodecadodecahedra, and 600 cubohemioctahedra. Two small ditrigonary icosidodecahedra, six great icosicosidodecahedra, six rhombidodecadodecahedra, 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.
