7-2 gyrochoron

The 7-2 gyrochoron, also known as mobius 7, is a convex isochoric polychoron with 7 edge-truncated tetrahedra as cells. It is also the triangular funk prism.

Isogonal derivatives
Substitution by vertices of these following elements will produce these convex isogonal polychora:
 * Edge-truncated tetrahedron (7): 7-2 step prism
 * Mirror-symmetric pentagon (7): 7-2 step prism
 * Kite (7): 7-2 step prism
 * Isosceles triangle (7): 7-2 step prism
 * Edge (7): 7-2 step prism
 * Edge (14): 14-3 step prism
 * Vertex (7): 7-2 step prism
