each set contains 8 solid models, 130 faces, 140 vertices, and 246 edge. We've carefully followed Euclid's Elements, Kepler's Mysterium Cosmographicum, and Plato's Timaeus. Every one of the five Platonic Solids have congruent convex regular polygons, each face meeting another identical face at an edge. And the extra three geometric solids are all Johnson solids.

Many of these surfaces were originally discovered by Alan Schoen in his famous 1970 NASA technical report Infinite Periodic Minimal Surfaces without Self-Intersection.
