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