Small biomnitruncatotetracontoctachoron

The rectangular frustic biomnitruncatotetracontoctachoron is a convex isogonal polychoron that consists of 48 great rhombicuobctahedra, 144 ditetragonal trapezoprisms, 192 ditrigonal prisms, 288 rectangular trapezoprisms and 576 rectangular frustums obtained as the convex hull of two opposite great prismatotetracontoctachora with F4 symmetry.
