%N a(n) = the n-th divisor of Fibonacci(n)^n (when the positive divisors of Fibonacci(n)^n are written in order from smallest to largest).

%C a(2)=0 because Fibonacci(2)^2=1 has no second divisor.

%e 1, 3, 7, 9, 21, 27, 49, 63, 81, 147, 189, 243, 343, 441, 567, 729,... is the beginning of the sequence of divisors of Fibonacci(8)^8 = 37822859361. 63 is the 8th term, so a(8) = 63.
