%N a(n) is the smallest number k such that Fibonacci(k) is a multiple of primorial(n).
%C Because the Fibonacci numbers form a divisibility sequence, each term of this sequence is a multiple of the previous term. The multiple can be computed using A001602. - _T. D. Noe_, May 04 2009

%F a(n) = lcm(A001602(1),...,A001602(n)). - _T. D. Noe_, May 04 2009
%e a(2)=12 because 12th Fibonacci number (144) is the smallest Fibonacci number which is a multiple of primorial(2), i.e., 6.
