Great prismatohexacosihecatonicosihecatonicosachoron

The great prismatohexacosihecatonicosihecatonicosachoron, or gippixhihy, is a nonconvex uniform polychoron that consists of 1200 triangular prisms, 600 octahemioctahedra, 120 quasitruncated great stellated dodecahedra, and 120 great quasitruncated icosidodecahedra. 1 triangular prism, 1 octahemioctahedron, 1 quasitruncated great stellated dodecahedron, and 2 great quasitruncated icosidodecahedra join at each vertex.

It is in the same regiment as the quasiprismatorhombated grand hexacosichoron.
