A polyhedron consisting of a -gon, a parallel -gon rotated a half-edge turn, and a band of paired triangles
separated by pentagons. The only true member giving a polyhedron consisting of all
regular polygons with unit edge lengths is the pentagonal
rotunda. It corresponds to half of an icosidodecahedron.
