Partially-rectified small swirlprism

The partially-rectified small swirlprism, also known as the amboprismatic transitional didecafold icosidodecaswirlchoron, is an isogonal polychoron that consists of 120 chiral rectified pentagonal prisms, 120 pentagonal prisms, and 600 vertices. 3 rectified pentagonal prisms and 2 pentagonal prisms join at each vertex. It can be constructed by general rectification of a transitive set of 600 edges of a small swirlprism.

It can also be constructed as a subsymmetrical faceting of the rectified hecatonicosachoron.

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