Small dipentary hexacosihecatonicosihexacositrishecatonicosachoron

The small dipentary hexacosihecatonicosihexacositrishecatonicosachoron, or sidpixhixthi, is a nonconvex uniform polychoron that consists of 120 small stellated dodecahedra, 120 icosahedra, 600 cuboctahedra, 120 rhombidodecadodecahedra, 600 truncated tetrahedra, and 120 truncated icosahedra. One small stellated dodecahedron, one icosahedron, five cuboctahedra, five rhombidodecadodecahedra, five truncated tetrahedra, and five truncated icosahedra join at each vertex.

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