8-2 gyrochoron

The 8-2 gyrochoron, also known as mobius 8, is a convex isochoric polychoron and member of the gyrochoron family. with 8 ridge-truncated wedges as cells. It is one of three isochoric polychora with 8 cells, the others being the regular tesseract and tetrahedral bipyramid.

Each cell of this polychoron has mirror symmetry, and contains 2 hexagons, 3 tetragons, and 2 triangles for faces, and shares a face with every other cell.

Isogonal derivatives
Substitution by vertices of these following elements will produce these convex isogonal polychora:
 * Ridge-truncated wedge (8): 8-2 step prism
 * Mirror-symmetric hexagon (8): 8-2 step prism
 * Kite (8): 8-2 step prism
 * Isosceles triangle (8): 8-2 step prism
 * Edge (8): 8-2 step prism
 * Edge (16): 16-2 step prism
 * Vertex (8): 8-2 step prism
