If the definition of regular polyhedra is not restricted to convex figures, their number rises from live to nine. The additional four are depicted in Figure 2-66 (for more information, see, e.g.. Refs. [2-59] and 2-63 - 2-66]). I hey are called by the common name of regular star polyhedra. One of them, viz., the great stellated dodecahedron, is illustrated by the decoration at the top of the Sacristy of St. Peter s Basilica in Vatican City, and another, the small stellated dodecahedron, by an ordinary lamp in Figure 2-67.
