Small tritrigonary disprismatohecatonicosihexacosihecatonicosachoron

The small tritrigonary disprismatohecatonicosihexacosihecatonicosachoron, or stut diphixhi, is a nonconvex uniform polychoron that consists of 600 tetrahedra, 120 truncated icosahedra, 120 small dodecicosidodecahedra, 1200 hexagonal prisms, and 720 decagonal prisms. One tetrahedron, three truncated icosahedra, three small dodecicosidodecahedra, six hexagonal prisms, and six decagonal prisms join at each vertex.

It also has compound of five cubes as pseudofacets.

Vertex coordinates
Its vertices are the same as those of its regiment colonel, the small tritrigonary prismatohecatonicosidishexacosichoron.
