The great faceted hexacosichoron, or gofix, also commonly called the great icosahedral 120-cell, is one of the 10 regular Schläfli–Hess polychora. It has 120 great icosahedra as cells, joining 5 to an edge and 12 to a vertex in the form of a small stellated dodecahedron.

The great faceted hexacosichoron is a faceting of the great stellated hecatonicosachoron, sharing its vertices and edges. The cells are in the same planes as the small stellated dodecahedra of the grand stellated hecatonicosachoron.
