Bergman polyhedra

The third window for the a positions, which are the centres of the Bergman polyhedra, is a triacontahedron of edge length t , see Figure 12-9. Both presented Wq and Wj windows in Figures 12-6 and 12-7 have some fixed, deterministic points and some probabilistic positions [4]. To obtain a completely deterministic model, we require that the minimal atomic distances along the fivefold, twofold and... [Pg.260]
