Prismatic transitional biomnitruncatotetracontoctachoron

The prismatic transitional biomnitruncatotetracontoctachoron or petbotic is a convex isogonal polychoron that consists of 48 great rhombicuboctahedra, 144 ditetragonal trapezoprisms and 192 orthoaligned truncated triangular prisms obtained as the convex hull of two opposite great prismatotetracontoctachoron with F4 symmetry.

This polychoron can be alternated into a prismatic transitional omnisnub bitetracontoctachoron, which is also nonuniform.

Using the ratio method, the lowest possible ratio between the longest and shortest edges is 1:$$\frac{2+\sqrt2}{2}$$ ≈ 1:1.70711.
