Small tripesic hecatonicosachoron

The small tripesic hecatonicosachoron, or sitphi, is a nonconvex noble fissary uniform polychoron that consists of 120 truncated great 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 small ditetrahedronary hexacosihecatonicosachoron.

A double cover of this polychoron can be seen as the bitruncated grand stellated hecatonicosachoron.
