Notched triacontachoron

The notched triacontachoron is a convex isochoric polychoron with 30 notches as cells. It can be obtained as the dual of the small 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 $$\frac67 ≈ 0.85714$$.

The ratio between the longest and shortest edges is 1:$$\frac{21}{8} = 2.625$$.
