It can be constructed as a rhombicosidodecahedron with two opposing pentagonal cupolae rotated through 36 degrees. {{Johnson solid}}Alternative Johnson solids, constructed by rotating different cupolae of a rhombicosidodecahedron, are: the gyrate rhombicosidodecahedron (J72) where only one cupola is rotated, the metabigyrate rhombicosidodecahedron (J74) where two non-opposing cupolae are rotated and the trigyrate rhombicosidodecahedron (J75) where three cupolae are rotated.
