Great tritrigonary hexacositrishecatonicosachoron

The great tritrigonary hexacositrishecatonicosachoron, or getit xethi, is a nonconvex uniform polychoron that consists of 600 regular tetrahedra, 120 quasitruncated great stellated dodecahedra, 120 great dodecicosidodecahedra, and 120 small ditrigonary icosidodecahedra. 1 tetrahedron, 3 quasitruncated great stellated dodecahedra, 3 great dodecicosidodecahedra, and 1 small ditrigonary icosidodecahedron join at each vertex.

The great tritrigonary hexacositrishecatonicosachoron contains the vertices of an inscribedgreat quasitruncaated icosidodecahedral prism.
