Trigyrate rhombicosidodecahedron

The trigyrate rhombicosidodecahedron, or tagyrid, is one of the 92 Johnson solids (J75). It consists of 1+1+3+3+6+6 triangles, 3+3+3+3+6+6+6 squares, and 3+3+3+3 pentagons. It can be constructed by rotating three mutually non-adjacent pentagonal cupola]]ic caps of the small rhombicosidodecahedron by 36º.
