Medial deltoidal hexecontahedron

The kites have two angles of ${\displaystyle \arccos({\frac {1}{6}})\approx 80.405\,931\,773\,14^{\circ }}$, one of ${\displaystyle \arccos(-{\frac {1}{8}}+{\frac {7}{24}}{\sqrt {5}})\approx 58.184\,446\,117\,59^{\circ }}$ and one of ${\displaystyle \arccos(-{\frac {1}{8}}-{\frac {7}{24}}{\sqrt {5}})\approx 141.003\,690\,336\,13^{\circ }}$. The dihedral angle equals ${\displaystyle \arccos(-{\frac {5}{7}})\approx 135.584\,691\,402\,81^{\circ }}$. The ratio between the lengths of the long and short edges is ${\displaystyle {\frac {27+7{\sqrt {5}}}{22}}\approx 1.938\,748\,901\,931\,75}$. Part of each kite lies inside the solid, hence is invisible in solid models.
