%N A058011 Consider the sequence {b(m)} of nonprimes; sequence gives values of m 
               where gcd{m, b(m)} increases.
%e A058011 a(4) = 8 because eight is the fourth nonprime number and GCD(4,8) > GCD(3,
               6).
%t A058011 r=0; Do[a = GCD[n, n - PrimePi[n] ]; If[a > r, r = a; Print[n]], {n, 
               1, 10^5} ]
