There are Nine Regular Solids, Not Just Five

Volume 3, Issue 2
Spring 1993

Mathematica can be used not only to draw the five Platonic solids but also to show the other four regular polyhedra. These less well known regular solids are discussed and are related to one another and to the regular dodecahedron and icosahedron. Mention is also made of the corresponding numbers of regular solids in dimensions other than three.
