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. 4 gyraed rectified triangular prisms and 2 triangular prisms join at each vertex. However, it cannot be made scaliform.

It can be constructed by removing the vertices of two inscribed hexacosichora of edge length $$\frac{\sqrt2+\sqrt{10}}{2}$$ from a hecatonicosachoron.

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