Great dodecicosacron
In geometry, the great dodecicosacron is the dual of the great dodecicosahedron. It has 60 intersecting bow-tie-shaped 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 golden ratio. Part of each face lies inside the solid, hence is invisible in solid models.
