Pyritohedral antitegum

The pyritohedral antitegum is a convex isochoric polychoron with 24 triangular-pentagonal gyronotches as cells.

Isogonal derivatives
Substitution by vertices of these following elements will produce these convex isogonal polychora:
 * Kite (12): Octahedral prism
 * Tetragon (24): Pyritohedral icosahedral antiprism
 * Scalene triangle (48): Bialternatosnub octahedral hosochoron
 * Edge (16): Tesseract
 * Edge (24): Pyritohedral icosahedral antiprism
 * Edge (48): Bialternatosnub octahedral hosochoron
 * Vertex (24): Pyritohedral icosahedral antiprism
