No other term <= Fibonacci(10000). - Emeric Deutsch, Jul 23 2006
No other term <= Fibonacci(10^8). - D. S. McNeil, Dec 08 2009
No other term <= Fibonacci(10^12). This sequence is almost certainly complete; in a random model the expected number of additional terms is less than 10^(-10000000000). - Charles R Greathouse IV, Sep 25 2012
