COMMENTS

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

LINKS

Table of n, a(n) for n=1..36.

EXAMPLE

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

PROG

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

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

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

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

CROSSREFS
