Transitional 1-bitridodecahedral swirlprism

The gyrorhombatoprismatic 1-bitridodecahedral swirlprism is a convex isogonal polychoron, formed as a convex hull of three hexacosichora in a way that leaves eighteen corealmic vertices corresponding to a gyrocantellated triangular prism. It consists of 120 gyrocantellated triangular prisms, 120 triangular prisms and 720 phyllic disphenoids of two kinds.

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