%N A064082 Zsigmondy numbers for a = 6, b = 1: Zs(n, 6, 1) is the greatest divisor 
               of 6^n - 1^n (A024062) that is relatively prime to 6^m - 1^m for 
               all positive integers m < n.
%C A064082 By Zsigmondy's theorem, the n-th Zsigmondy number for bases a and b is 
               not 1 except in the three cases (1) a = 2, b = 1, n = 1, (2) a = 
               2, b = 1, n = 6, (3) n = 2 and a+b is a power of 2.
