In geometry, the great icosidodecahedron is a nonconvex uniform polyhedron, indexed as U54.
This polyhedron can be considered a rectified great icosahedron.
It shares the same vertex arrangement with the icosidodecahedron.
Unlike the great icosahedron and great dodecahedron, the great icosidodecahedron is not a stellation of the icosidodecahedron.
