Great biomnitruncatotetracontoctachoron

The great biomnitruncatotetracontoctachoron or gabotic is a convex isogonal polychoron that consists of 48 great rhombicuboctahedra, 144 ditetragonal trapezoprisms, 192 ditrigonal prisms, 384 ditrigonal frustums, and 288 rectangular trapezoprisms. 2 ditrigonal furstums and 1 of each of the other 4 cell types join at each vertex.

It is one of a total of four distinct polychora (including two transitional cases) that can be obtained as the convex hull of two opposite great disprismatoicositetricositetrachora	 (that is, variants of the great prismatotetracontoctachoron with single F4 symmetry). If the great disprismatoicositetricositetrachora are of the form a3b4c3d, then the lacing edges generally have length $$\sqrt{(2-\sqrt2)(a-d)^2+(6-4\sqrt2)(b-c)^2+(6-4\sqrt2)(a-d)(b-c)}$$.

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