In geometry, a deltoidal hexecontahedron (also sometimes called a trapezoidal hexecontahedron, a strombic hexecontahedron, or a tetragonal hexacontahedron[1]) 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.

Orthogonal projections[edit]

The deltoidal hexecontahedron has 3 symmetry positions located on the 3 types of vertices:

This tiling is topologically related as a part of sequence of deltoidal polyhedra with face figure (V3.4.n.4), and continues as tilings of the hyperbolic plane. These face-transitive figures have (*n32) reflectional symmetry.
