First kipentagrammic hexecontahedron

The  is a noble polyhedron. Its 60 congruent faces are irregular pentagrams meeting at congruent order-5 vertices. It is a faceting of a semi-uniform truncated icosahedron hull.

The ratio between the shortest and longest edges is 1:$$\sqrt{\frac{5+2\sqrt5}{5}}$$ ≈ 1:1.37638.
