Swirlprismatostellated bijungatotetracontoctachoron

The 1-pyritohedral small rhombicuboctahedral swirltegum is an isochoric polychoron with 144 identical cells. Together with its dual, it is the first in an infinite family of small rhombitetratetrahedral swirlchora.

Isogonal derivatives
Substitution by vertices of these following elements will produce these convex isogonal polychora:
 * Unnamed cell (144): Swirlprismatodiminished biambotetracontoctachoron
 * Triangle (24): Icositetrachoron
 * Kite (72): Swirlprismatodiminished rectified icositetrachoron
 * Isosceles triangle (72): Swirlprismatodiminished rectified icositetrachoron
 * Edge (24): Icositetrachoron
 * Vertex (24): Icositetrachoron
