Small 13-5 double step prism

The 13-5 double step prism is a convex isogonal polychoron that consists of 13 rhombic disphenoids, 26 phyllic disphenoids and 104 irregular tetrahedra of two kinds obtained as the convex hull of two orthogonal 13-5 step prisms.

Isogonal derivatives
Substitution by vertices of these following elements will produce these convex isogonal polychora:
 * Rhombic disphenoid (13): 13-5 step prism
 * Phyllic disphenoid (26): 13-5 double step prism
 * Scalene triangle (26): 13-5 double step prism
 * Edge (13): 13-5 step prism
 * Edge (26): 13-5 double step prism
