The transitional bicantitruncatodecachoron or tabcatic is a convex isogonal polychoron that consists of 48 truncated cubes, 144 ditetragonal trapezoprisms and 192 triangular trapezorhombihedra obtained as the convex hull of two opposite great rhombated icositetrachora.

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