Great tritrigonary disprismatohecatonicosihexacosihecatonicosachoron

The great tritrigonary disprismatohecatonicosihexacosihecatonicosachoron, or getit diphixhi, is a nonconvex uniform polychoron that consists of 600 tetrahedra, 120 truncated great icosahedra, 120 great dodecicosidodecahedra, 1200 hexagonal prisms, and 720 decagrammic prisms. One tetrahedron, three truncated great icosahedra, three great dodecicosidodecahedra, six hexagonal prisms, and six decagrammic prisms join at each vertex.

It also has compound of five cubes as pseudofacets.

Vertex coordinates
Its vertices are the same as those of its regiment colonel, the great tritrigonary hexacositrishecatonicosachoron.
