Great biprismatorhombatodecachoron

The great biprismatorhombatodecachoron or gabipard is a convex isogonal polychoron that consists of 10 truncated tetrahedra, 20 ditrigonal prisms, 30 rectangular trapezoprisms, 20 triangular antiprisms, and 60 wedges. 1 truncated tetrahedron, 2 ditrigonal prisms, 2 rectangular trapezoprisms, 1 triangular antiprism, and 3 wedges join at each vertex.

It is one of a total of five distinct polychora (including two transitional cases) that can be obtained as the convex hull of two opposite prismatorhombated pentachora. In this case, if the prismatorhombated pentachora are of the form a3b3o3c, then c must be greater than a+2b (producing the truncated small prismatodecachoron in the limiting case). The lacing edges generally have length $$\sqrt{\frac{3a^2+2b^2+3c^2+2ab-6ac-2bc}{5}}$$.
