Swirlprismatodiminished biambotetracontoctachoron

The swirlprismatodiminished biambotetracontoctachoron is an isogonal polychoron with 48 triangular antiprisms, 96 triangular frustums, 144 tetragonal antiwedges and 144 vertices.

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

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