Small tritrigonary hexacosihecatonicosidishecatonicosachoron

The small tritrigonary hexacosihecatonicosidishecatonicosachoron, or stut xhidy, is a nonconvex uniform polychoron that consists of 600 tetrahedra, 120 small dodecicosidodecahedra, 120 truncated icosahedra, and 120 small dodecicosahedra. One tetrahedron, three small dodecicosidodecahedra, three truncated icosahedra, and three small dodecicosahedra join at each vertex.

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