Small rhombidodecacron
In geometry, the small rhombidodecacron is a nonconvex isohedral polyhedron. It is the dual of the small rhombidodecahedron. It is visually identical to the Small dodecacronic hexecontahedron. It has 60 intersecting antiparallelogram faces. Proportions. Each face has two angles of formula_1 and two angles of formula_2. The diagonals of each antiparallelogram intersect at an angle of formula_3. The ratio between the lengths of the long edges and the short ones equals formula_4, which is the golden ratio. The dihedral angle equals formula_5.
