Small pseudorhombic prismatohecatonicosachoron

The small pseudorhombic prismatohecatonicosachoron, or spriphi, is a nonconvex uniform polychoron that consists of 120 truncated dodecahedra, 1200 triangular prisms, and 720 decagonal prisms. Two truncated dodecahedra, two triangular prisms, and four decagonal prisms join at each vertex.

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