EXAMPLE
a(1)=54 because 54th Fibonacci number (i.e., 86267571272) consists of 8 prime factors (i.e., 2*2*2*17*19*53*109*5779).
MATHEMATICA
t = {}; Do[f = FactorInteger[Fibonacci[n]]; If[Total[Transpose[f][[2]]] == 8, AppendTo[t, n]], {n, 2, 200}]; t (* T. D. Noe, Mar 14 2014 *)
PROG
(PARI) n=1; while(n<320, if(bigomega(fibonacci(n))==8, print1(n, ", ")); n++)
