In geometry, a deltoidal hexecontahedron (also sometimes called a trapezoidal hexecontahedron, a strombic hexecontahedron, or a tetragonal hexacontahedron) is a catalan solid which looks a bit like either an overinflated dodecahedron or icosahedron. It is sometimes also called the trapezoidal hexecontahedron or strombic hexecontahedron. Its dual polyhedron is the rhombicosidodecahedron.
The 60 faces are deltoids or kites (not trapezoidal). The short and long edges of each kite are in the ratio 1.00:1.54.
It is the only Archimedean dual which does not have a Hamiltonian path among its vertices.
