1-great rhombitetratetrahedral swirltegum

The 1-great rhombitetraterahedral swirltegum is a convex isochoric polychoron with 144 mirror-symmetric notches as cells. Together with its dual, it is the first in an infinite family of great rhombitetratetrahedral swirlchora.

Isogonal derivatives
Substitution by vertices of these following elements will produce these convex isogonal polychora:
 * Mirror-symmetric notch (144): Swirlprismatodiminished rectified icositetrachoron
 * Isosceles triangle (72): Swirlprismatodiminished rectified icositetrachoron
 * Scalene triangle (144): Bi-icositetradiminished truncated icositetrachoron
 * Edge (24): Icositetrachoron
 * Edge (72): Swirlprismatodiminished rectified icositetrachoron
 * Edge (144): Bi-icositetradiminished truncated icositetrachoron
 * Vertex (24): Icositetrachoron
