The third noble unihexagrammic hexecontahedron is a noble polyhedron. Its 60 congruent faces are rectangular-symmetric unicursal hexagrams meeting at congruent order-6 vertices. It is a faceting of a uniform small rhombicosidodecahedron hull.
The ratio between the shortest and longest edges is 1: ≈ 1:1.20300.
Vertex coordinates[edit | edit source]
Its vertices are the same as those of a small rhombicosidodecahedron.
