Archimedean solid
In geometry, a deltoidal hexecontahedron (also sometimes called a "trapezoidal hexecontahedron", a "strombic hexecontahedron", or a "tetragonal hexacontahedron") is a Catalan solid which is the dual polyhedron of the rhombicosidodecahedron, an Archimedean solid. It is one of six Catalan solids to not have a Hamiltonian path among its vertices.
