Small dipentary hexacosidishecatonicosachoron

The small dipentary hexacosidishecatonicosachoron, or sidpixady, is a nonconvex uniform polychoron that consists of 600 truncated tetrahedra, 120 truncated icosahedra, and 120 small dodecicosidodecahedra. Five truncated tetrahedra, five truncated icosahedra, and five small dodecicosidodecahedra join at each vertex.

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