The transitional biprismatorhombatodecachoron or tabipard is a convex isogonal polychoron that consists of 10 orthoaligned great rhombitetratetrahedra, 30 rectangular trapezoprisms and 20 triangular prisms obtained as the convex hull of two opposite prismatorhombated pentachora.

Using the ratio method, the lowest possible ratio between the longest and shortest edges is 1:$$\frac{3+\sqrt3}{3}$$ ≈ 1:1.57735.
