Swirlprismatodiminished biambotetracontoctachoron

The swirlprismatodiminished biambotetracontoctachoron is an isogonal polychoron with 48 triangular antiprisms, 98 triangular frustums, 144 tetragonal antiwedges and 144 vertices. Together with its dual, it is the first in an infinite family of pyritohedral small rhombicuboctahedral swirlchora.

It can be constructed by removing an inscribed tetradisphenoidal diacosioctacontoctachoron from a biambotetracontoctachoron.

Isogonal derivatives
Substitution by vertices of these following elements will produce these convex isogonal polychora:
 * Triangular antiprism (48): Tetradisphenoidal diacosioctacontoctachoron
 * Triangle (48): Tetradisphenoidal diacosioctacontoctachoron
 * Edge (144): Swirlprismatodiminished biambotetracontoctachoron
