These curves are, respectively, linear, quadratic, cubic, and quartic. Because the (32) n and (2)(32) n processes share boundary curves, the allowed regions are contiguous and non- overlapping. Furthermore, the asymptotes, having the basic form a = tan $^{2}$( π/ (2(2 m + 1))) , approach a = 0 in the limit as n approaches ∞ , and so the entire a − b plane above the line b = a is covered by allowed regions for processes of these types. The allowed regions for (32), (232), and (3232) are given in figure 3.
