Small ditrigonal prismatotrishecatonicosachoron

The small ditrigonal prismatotrishecatonicosachoron, or sid tipathi, is a nonconvex uniform polychoron that consists of 1200 triangular prisms, 120 truncated great icosahedra, 120 small ditrigonal dodecicosidodecahedra, and 120 great rhombicosidodecahedra. 1 triangular prism, 1 truncated great icosahedron, 1 small ditrigonal dodecicosidodecahedron, and 2 great rhombicosidodecahedra join at each vertex.

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