Notched diacosioctacontoctachoron

The notched diacosioctacontoctachoron is a convex isochoric polychoron with 288 notches as cells. It can be obtained as the dual of the small rhombated icositetrachoron.

It can also be constructed as the convex hull of 2 dual icositetrachora and a rectified icositetrachoron. If the larger icositetrachoron has edge length 1, the smaller pentachoron has edge length $$\frac{\sqrt2}{2} ≈ 0.70711$$ and the rectified pentachoron has edge length $$\frac{2+5\sqrt2}{23} ≈ 0.39439$$.
