Rhombicosacron
In geometry, the rhombicosacron is a nonconvex isohedral polyhedron. It is the dual of the uniform rhombicosahedron, U56. It has 50 vertices, 120 edges, and 60 crossed-quadrilateral faces.Proportions
Each face has two angles of and two angles of. The diagonals of each antiparallelogram intersect at an angle of. The dihedral angle equals. The ratio between the lengths of the long edges and the short ones equals, which is the square of the golden ratio.
