Hecatonicosadiminished hecatonicosachoron

The hecatonicosadiminished hecatonicosachoron or hidhi is a convex isogonal polychoron that consists of 120 propello tetrahedra and 120 tetrahedra. However, it cannot be made scaliform.

It can be constructed by removing an inscribed hexacosichoron of edge length $\sqrt{3+√5}$ from a hecatonicosachoron.

The ratio between the longest and shortest edges is 1:$$\frac{1+\sqrt5}{2}$$ ≈ 1:1.61803.
