Prismatic transitional omnisnub bidecachoron

The prismatic transitional omnisnub bidecachoron or petosbid is a convex isogonal polychoron that consists of 10 snub tetrahedra, 20 gyrated rectified triangular prisms, 20 triangular antiprisms, and 120 irregular tetrahedra. 1 snub tetrahedron, 2 gyrated rectified triangular prisms, 1 triangular antiprism, and 4 irregular tetrahedra join at each vertex. It can be obtained through the process of alternating the prismatic transitional biomnitruncatodecachoron.

Using the ratio method, the lowest possible ratio between the longest and shortest edges is 1:$$\frac{\sqrt{38}}{4}$$ ≈ 1:1.54110.
