Product Description
This figure is a dual pair with each element of the pair projected on to a separate sphere. The outside sphere is a Pentagonal Hexecontahedron, a Catalan Solid. The inner sphere is a Snub Dodecahedron which is an Archimedean solid. The dual nature of the pair is demonstrated by the facts that the inner figure has a vertex where the outer figure has a face- and vice versa. Each figure has an edge crossing at right angles to a corresponding edge on the other figure. This figure shows the beauty of geometry in a powerful way. There are thirteen such pairs (an Archimedean / Catalan dual) on this site. All are uniquely beautiful and intriguing.
