Medial icosacronic hexecontahedron

The medial icosacronic hexecontahedron is a uniform dual polyhedron. It consists of 60 darts.

If its dual, the icosidodecadodecahedron, has an edge length of 1, then the short edges of the darts will measure $$\frac{7\sqrt6-\sqrt{30}}{11} ≈ 1.06084$$, and the long edges will be $$\frac{7\sqrt6+\sqrt{30}}{11} ≈ 2.05670$$. ​The dart faces will have length $$\frac{6\sqrt7}{11} ≈ 1.44314$$, and width 2. ​The darts have two interior angles of $$\arccos\left(\frac34\right) ≈ 41.40962°$$, one of $$\arccos\left(-\frac18+\frac{7\sqrt5}{24}\right) ≈ 58.18445°$$, and one of $$360°-\arccos\left(-\frac18-\frac{7\sqrt5}{24}\right) ≈ 218.99631°$$.

Vertex coordinates
A medial icosacronic hexecontahedron with dual edge length 1 has vertex coordinates given by all even permutations of:
 * $$\left(±\frac{\sqrt5-1}{2},\,±\frac{1+\sqrt5}{2},\,0\right),$$
 * $$\left(±3\frac{7+\sqrt5}{22},\,±3\frac{3\sqrt5-1}{22},\,0\right),$$
 * $$\left(±3\frac{1+3\sqrt5}{22},\,±3\frac{7-\sqrt5}{22},\,0\right),$$
 * $$\left(±1,\,±1,\,±1\right).$$
