Swirlprismatodiminished tetracontoctachoron

The swirlprismatodiminished tetracontoctachoron is an isogonal polychoron with 48 tetrachirodiminished truncated cubes and 96 tetragonal disphenoids. 4 tetrachirodiminished truncated cubes and 2 tetragonal disphenoids join at each vertex.

It can be constructed by removing the 96 vertices of an inscribed octafold cuboctaswirlchoron from a tetracontoctachoron.

The ratio between the longest and shortest edges is 1:$$\sqrt{2+\sqrt2}$$ ≈ 1:1.84776.
