Small ditrigonary hexacosihecatonicosiprismatohecatonicosachoron

The small ditrigonary hexacosihecatonicosiprismatohecatonicosachoron, or sidtixhiphi, is a nonconvex uniform polychoron that consists of 120 ditrigonary dodecadodecahedra, 120 icosidodecadodecahedra, 720 decagrammic prisms, and 600 cubohemioctahedra. Two ditrigonary dodecadodecahedra, six icosidodecadodecahedra, twelve decagrammic prisms, 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.
