Tri-icositetradiminished hexacosichoron

The tri-icositetradiminished hexacosichoron, tetragonal-antiwedge heptacontadichoron, 1-bicubic swirlprism, or tridex, is a noble polychoron with 72 tetragonal antiwedges as cells. Together with its dual, it is the first in an infinite family of octahedral swirlchora. It can be obtained by diminishing the vertices of three icositetrachora from the hexacosichoron.
