The great tripesic hecatonicosachoron, or gitphi, is a nonconvex noble fissary uniform polychoron that consists of 120 quasitruncated small stellated dodecahedra as cells. 12 cells join at each vertex.

It is fissary due to having a compound vertex figure, specifically a compound of three disphenoids. It shares its edges with the grand ditetrahedronary hexacosidishecatonicosachoron.

A double cover of this polychoron can be seen as the biquasitruncated great hecatonicosachoron.
