%N Integers n such that A264137(n) < A060385(n).

%C For all corresponding values of n, A000129(n) is a composite number. In other words, n cannot be a term of A096650.

%e 52 is a term because A264137(52) = 66923 < A060385(52) = 90481.

%o (PARI) a060385(n) = my(f=factor(fibonacci(n))[, 1]); f[#f];

%o a000129(n) = ([2, 1; 1, 0]^n)[2, 1];

%o a264137(n) = my(p=factor(a000129(n))[, 1]); p[#p];

%o lista(nn) = for(n=3, nn, if(a264137(n) < a060385(n), print1(n, ", ")));

%Y Cf. A060385, A264137.
