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