The polyhedron above has 72 pentagonal faces of two types. The next one below has three different types of pentagon for its 132 faces. After that is a polyhedron with sixty faces, all of which are non-convex pentagons.

All three of these all-pentagon polyhedra were created using *Stella 4d: Polyhedron Navigator*. This program is available here.

Pingback: * Three Polyhedra with Only Pentagonal Faces — RobertLovesPi’s Blog | Teachezwell Blog

I love pentagons, although my preference is convex.

Question, is it possible to have a polyhedron of 240 convex pentagons?

I think it is, but I don’t have enough math background to determine if it is so.

I must admit that I simply do not know. If I find one, ever, I’ll post it on this blog.
