Small rhombic dishecatonicosachoron

The small rhombic dishecatonicosachoron, or sirdhi, is a nonconvex uniform polychoron that consists of 120 truncated dodecahedra, 120 small rhombidodecahedra, and 1200 triangular prisms. Two truncated dodecahedra, two small rhombidodecahedra, and two triangular prisms join at each vertex.

Vertex coordinates
The vertices are the same as those of the regiment colonel, the small rhombated hecatonicosachoron.
