Bi-hecatonicosadiminished hecatonicosachoron

The bi-hecatonicosadiminished hecatonicosachoron or bhidhi is a convex isogonal polychoron that consists of 120 gyrated rectified triangular prisms and 120 triangular prisms. However, it cannot be made scaliform.

It can be constructed by removing two inscribed hexacosichora 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.
