Small ditrigonary dishexacositetrishecatonicosachoron

The small ditrigonary dishexacositetrishecatonicosachoron, or sidtiduxthi, is a nonconvex uniform polychoron that consists of 120 great ditrigonary icosidodecahedra, 120 great icosidodecahedra, 600 octahedra, 120 icosidodecadodecahedra, 120 quasitruncated dodecadodecahedra, and 600 cubohemioctahedra. Two great ditrigonary icosidodecahedra, three great icosidodecahedra, three octahedra, six icosidodecadodecahedra, 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.
