In the "Mathsisfun" page, it says there are only 5 regular polyhedra ("the Platonic solids (or regular polyhedra)")

There are actually nine regular polyhedra, the 5 Platonic solids and the 4 Kepler-Poinsot solids. A Platonic solid is a regular "convex" polyhedron. The other 4 are star polyhedra.

Why did the chicken cross the Mobius Band?

To get to the other ...um...!!!

You have a point. I will remove the reference to "regular" until I can incorporate the star polyhedra.
