The dodecahedronary dishecatonicosachoron, or didhi, is a nonconvex uniform polychoron that consists of 120 great ditrigonary icosidodecahedra and 120 great icosahedra. Twenty great ditrigonary icosidodecahedra and twelve great icosahedra join at each vertex.
It also has tetrahedra as pseudofacets.
Vertex coordinates[edit | edit source]
Its vertices are the same as those of its regiment colonel, the small ditrigonary hexacosihecatonicosachoron.
