Truncated great ditrigonary hexacosihecatonicosachoron

The truncated great ditrigonary hexacosihecatonicosachoron, or tiggidtixhi, is a nonconvex uniform polychoron that consists of 600 truncated tetrahedra, 120 great ditrigonary icosidodecahedra, and 120 truncated icosahedra. 1 great ditrigonary icosidodecahedron, 3 truncated icosahedra, and 3 truncated tetrahedra join at each vertex. As the name suggests, it can be obtained by truncating the great ditrigonary hexacosihecatonicosachoron.

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