The great 13-5 double step prism is a convex isogonal polychoron that consists of 13 tetragonal disphenoids, 26 phyllic disphenoids, and 156 irregular tetrahedra of three kinds. 2 tetragonal disphenoids, 4 phyllic disphenoids, and 24 irregular tetrahedra join at each vertex. It can be obtained as the convex hull of two orthogonal 13-5 step prisms.
