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 inscribed great quasitruncated icosidodecahedral prism.
The vertices of a great tritrigonary hexacositrishecatonicosachoron of edge length 1 are all permutations of:
along with the even permutations of:
The great tritrigonary hexacositrishecatonicosachoron is the colonel of a regiment that contains 79 uniform members as well as 30 fissary uniforms.
