Great tritrigonary disprismatohecatonicosidishexacosichoron

The great tritrigonary disprismatohecatonicosidishexacosichoron, or getitid phiddix, is a nonconvex uniform polychoron that consists of 600 tetrahedra, 120 quasitruncated great stellated dodecahedra, 600 octahemioctahedra, 1200 hexagonal prisms, and 720 decagrammic prisms. One tetrahedron, three quasitruncated great stellated dodecahedra, three octahemioctahedra, 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.
