Printing Johnson Solids

Posted on July 21, 2012

Norman Johnson is Professor Emeritus of Mathematics here at Wheaton. In 1966, he identified a collection of polyhedra that are convex and have non-uniform regular polygonal faces: the Johnson Solids. There are 92 in total -- excluding prisms and antiprisms. We're in the process of printing out all of them!

Above we are printing J42 (an Elongated Pentagonal Orthobirotunda). Below we are printing J60 (a Metabiaugmented Dodecahedron). A complete list of the Johnson Solids with interactive graphics is available at Eric Weisstein's Mathworld.
