Hecatonicosihexacosiquasitruncated hexacosihecatonicosachoron

The hecatonicosihexacosiquasitruncated hexacosihecatonicosachoron, or hixquitixhi, is a nonconvex uniform polychoron that consists of 600 truncated tetrahedra, 120 quasitruncated small stellated dodecahedra, 120 small dodecicosidodecahedra, and 120 icosidodecatruncated icosidodecahedra. 1 truncated tetrahedron, 1 quasitruncated small stellated dodecahedron, 1 small dodecicosidodecahedron, and 2 icosidodecatruncated icosidodecahedra join at each vertex.

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