An Unusual Polyhedron with 200 Faces

This polyhedron was made from the faceted rhombicosidodecahedron in the post immediately before this one, by stellating it a few times. Its 200 faces include twenty equilateral triangles (yellow), sixty irregular decagons (green), and two sets of sixty trapezoids each (red and blue). I made it using Stella 4d, which you can try for free at

An Enneacontahedron Made of Hexagons and Rhombi

An enneacontahedron is a polyhedron with ninety faces. There are many such polyhedra. This particular one has sixty hexagonal faces, and thirty rhombic faces. I made it using Stella 4d, a program you can try for free at
