Great disprismatoicositetricositetrachoron

The great disprismatoicositetricositetrachoron is a convex semi-uniform polychoron that is a variant of the great prismatotetracontoctachoron with only regular icositetrachoric and not doubled icositetrachoric symmetry. As such it can be represented by a3b4c3d, and has 48 great rhombicuboctahedra of two types, forms c4b3a and b4c3d) and 192 ditrigonal prisms (two types, forms a c3d and d a3b) as cells, with 4 edge lengths. It is the most complex isogonal polytope generally possible with F4 symmetry.

It can generally be alternated into a snub icositetrachoron, which is also not uniform.
