Truncated ditrigonary dishecatonicosachoron

The truncated ditrigonary dishecatonicosachoron, or tidtidohi, is a nonconvex uniform polychoron that consists of 120 ditrigonary dodecadodecahedra, 120 truncated icosahedra, and 120 truncated great icosahedra. 1 ditrigonary dodecadodecahedron, 3 truncated icosahedra, and 3 truncated great icosahedra join at each vertex. As the name suggests, it can be obtained by truncating the ditrigonary dishecatonicosachoron.

It is in the same regiment as the truncated small ditrigonary hexacosihecatonicosachoron.
