Great dodecacronic hexecontahedron
In geometry, the great dodecacronic hexecontahedron is a nonconvex isohedral polyhedron. It is the dual of the uniform great dodecicosidodecahedron. Its 60 intersecting quadrilateral faces are kites. Part of each kite lies inside the solid, hence is invisible in solid models.Proportions
Each kite has two angles of, one of and one of. The dihedral angle equals. The ratio between the lengths of the long and short edges is.
