Two Views of an Icosahedron, Augmented with Great Icosahedra
If colored by facetype, based on faceposition in the overall solid, this “cluster” polyhedron looks like this: There is another interesting view of this polyhedral cluster I like marginally better, though, and that is to separate the faces into colorgroups … Continue reading

A Polyhedron with Exactly 200 Faces
Sixty of the faces of this polyhedron are pentagons (orange), and the other 140 are hexagons of three types (blue, pink, and purple). I made it using Stella 4d, a program available at http://www.software3d.com/Stella.php.

The “Trick Johnson” (?) — A NearMiss Johnson Solid, Surrounded by Hilariously Mistranslated Japanese
I did not discover this polyhedron, although I wish I had, for it has quite a clever design. The page where I found it (poorlytranslated English version, where it’s called the “Trick Johnson,” whatever that means) is at http://www.geocities.jp/ikuro_kotaro/koramu/1053_g2.htm).

NearMiss Candidate Update #1
With help from friends on Facebook, I was able to figure out how to make the second of the nearmiss candidates in the last post, using Stella 4d: Polyhedron Navigator, a program available here. This is quite helpful, for Stella … Continue reading
