Parabigyrate rhombicosidodecahedron

The parabigyrate rhombicosidodecahedron, or pabgyrid, is one of the 92 Johnson solids (J73). It consists of 10+10 triangles, 10+10+10 squares, and 2+10 pentagons. It can be constructed by rotating two opposite pentagonal cupolaic caps of the small rhombicosidodecahedron by 36º.
