The great icosacronic hexecontahedron is a uniform dual polyhedron. It consists of 60 darts.
If its dual, the great icosicosidodecahedron, has an edge length of 1, then the short edges of the darts will measure , and the long edges will be . The dart faces will have length , and width . The darts have two interior angles of , one of , and one of .
