Deltopyramidal heptachiliadiacosichoron

The deltopyramidal heptachiliadiacosichoron is a convex isochoric polychoron with 7200 kite pyramids as cells. It can be obtained as the dual of the prismatorhombated hecatonicosachoron.

It can also be constructed as the convex hull of a hecatonicosachoron, a hexacosichoron, a rectified hexacosichoron, and a rectified hecatonicosachoron. If the hecatonicosachoron has edge length 1, the hexacosichoron has edge length $$\frac{61+29\sqrt5}{82} ≈ 2.35235$$, the rectified hexacosichoron has edge length $$\frac{101+31\sqrt5}{142} ≈ 1.19942$$, and the rectified hecatonicosachoron has edge length $$\frac{10+\sqrt5}{15} ≈ 0.81574$$.
