Isogonal derivatives
Substitution by vertices of these following elements will produce these convex isogonal polychora:
 * Triangular bipyramid (96): Rectified icositetrachoron
 * Isosceles triangle (288): Small rhombated icositetrachoron
 * Edge (96): Rectified icositetrachoron
 * Edge (144): Semi-uniform small prismatotetracontoctachoron
 * Vertex (24): Icositetrachoron
 * Vertex (24): Icositetrachoron
