Swirlprismatostellated joined icositetrachoron

The 1-small rhombitetratetrahedral swirltegum is a convex isochoric polychoron with 72 tetragonal-ridge stellated tetragonal antiwedges as cells. Together with its dual, it is the first in an infinite family of small rhombitetratetrahedral swirlchora.
