Our d60 is based on the deltoidal hexecontahedron. This will be the first injection-molded d60. This polyhedron is the only fully-symmetric hexecontahedron with opposing parallel faces. There are so many choices for numbering the faces that it wasn't practical to compute all of them. A solution was found that perfectly balances the sums for all twelve groups of five faces and all twenty groups of three faces. The polyhedron also has thirty groups of four faces, but these don't jump out to the eye as readily, as they again have two short and two long edges meeting in a group. The sums for these aren't particularly well balanced.
