Small dipentary trishecatonicosiprismatohexacosichoron

The small dipentary trishecatonicosiprismatohexacosichoron, or sidpithipix, is a nonconvex uniform polychoron that consists of 120 great dodecahedra, 1200 triangular prisms, 600 octahemioctahedra, 120 small rhombicosidodecahedra, and 120 small dodecicosahedra. One great dodecahedron, five triangular prisms, five octahemioctahedra, five small rhombicosidodecahedra, and five small dodecicosahedra join at each vertex.

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