Triangular 1-icosidodecahedral swirlprism

The triangular 1-icosidodecahedral swirlprism is an isogonal polychoron that consists of 120 chiral rectified triangular prisms, 120 triangular gyroprisms, 240 triangular antipodiums, and 360 vertices. 3 rectified triangular prisms, 2 triangular gyroprisms, and 4 triangular antipodiums join at each vertex. 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.
