Great dodecacronic hexecontahedron
Introduction 3D model of a great dodecacronic hexecontahedronIn geometry, the '''great dodecacronic hexecontahedron''' (or '''great lanceal ditriacontahedron''') 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 .
