Great hecatonicosihecatonicosachoron

The great hecatonicosihecatonicosachoron, or ghihi, is a nonconvex uniform polychoron that consists of 120 quasitruncated small stellated dodecahedra and 120 quasitruncated great stellated dodecahedra. 2 quasitruncated small stellated dodecahedra and 2 quasitruncated great stellated dodecahedra join at each vertex. It can be seen as the biquasitruncate of either the great grand hecatonicosachoron or its dual great faceted hexacosichoron.
