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

I made this faceting of the rhombicosidodecahedron using Stella 4d: Polyhedron Navigator. You can try this program out, for free, at

The Great Icosidodecahedron and Its Dual, the Great Rhombic Triacontahedron

The great icosidodecahedron is one of the uniform polyhedra, which I do not know well. I stumbled across it while creating facetings of the (lesser) icosidodecahedron. This solid has two face-types, there are red pentagrams and yellow equilateral triangles, as seen in the next two pictures.

The dual of this solid is the great rhombic triacontahedron. Its faces are thirty interpenetrating rhombi.

I used Stella 4d to create these images. You may try this program for free at

Simulated Geomag Rhombicosidodecahedron

This rhombicosidodecahedron appears to be made from Geomag pieces, but, in reality, it was made virtually using a program called Stella 4d. You may try Stella, for free, at

A Symmetrohedron with 122 Faces

In this symmetrohedron, all faces are regular, except for the green isosceles triangles. If these triangles were a little closer to being regular, this would be a near-miss to the Johnson solids, but that is not the case. I made this (starting with the last polyhedron in the post right before this one) using Stella 4d: Polyhedron Navigator, a program you can try for free at
