Great biprismatorhombatotetracontoctachoron

The great biprismatorhombatotetracontoctachoron or gabiparc is a convex isogonal polychoron that consists of 48 truncated tetrahedra, 192 ditrigonal prisms, 144 square antiprisms, 288 rectangular trapezoprisms, and 576 wedges. 1 truncated octahedron, 2 ditrigonal prisms, 1 square antiprism, 2 rectangular trapezoprisms, 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 icositetrachora. In this case, if the prismatorhombated icositetrachora are of the form a3b4o3c, then c must be greater than a+2b (producing the truncated small prismatotetracontoctachoron in the limiting case). The lacing edges generally have length $$\sqrt{(6-4\sqrt2)b^2+(6-4\sqrt2)a(b-c)+(6-4\sqrt2)(b-c)^2+(2-\sqrt2)(a-c)^2}$$.
