Self Dual Tetracontahedron Pattern 6 Greater Self Dual Solids Pendant and Keychain – Mathematical Geometry in a Compact Form Enter the rarified realm of geometric self-reference with this Greater Self-Dual Solids keychain and pendant set, meticulously crafted for 3D printing. A self-dual solid is one of mathematics' most philosophically compelling objects — a polyhedron whose dual, constructed by replacing every face with a vertex and every vertex with a face, produces a form identical in structure to the original. The greater self-dual solids extend this principle into spectacular star-like territory, encompassing elevated and stellated forms where spiky pyramidal peaks replace flat faces, creating objects of dramatic visual complexity that nonetheless possess the rare and beautiful property of perfect self-correspondence. These are solids that mirror themselves across the boundary between face and vertex — geometry folding back upon its own definition with absolute…
