Sphenoidal hexecontachoron

The sphenoidal hexecontachoron is a convex isochoric polychoron with 60 sphenoids as cells. It can be obtained as the dual of the great rhombated pentachoron.

It can also be constructed as the convex hull of 2 dual pentachora and a rectified pentachoron. If the smaller pentachoron has edge length 1, the larger pentachoron has edge length $$\frac32 = 1.5$$ and the rectified pentachoron has edge length $$\frac{9}{13} ≈ 0.69231$$.
