Partially-rectified small swirlprism

The pentagonal 1-icosidodecahedral swirlprism is an isogonal polychoron that consists of 120 chiral rectified pentagonal prisms, 120 pentagonal prisms and 600 vertices. Together with its dual, it is the first in an infinite family of icosidodecahedral swirlchora.

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