%S A167023 5,34,144,46368
%N A167023 Fibonacci numbers where both neighbors are semiprimes.
%C A167023 Next term (if it exists) is larger than 10^10000. I conjecture that this sequence is finite: if neighbors of Fibonacci numbers behave randomly, the expected number of remaining terms is about 0.0103 (or 0.00779 if their behavior mod 6 is taken into account). - _Charles R Greathouse IV_, Nov 09 2009
%F A167023 A124936 INTERSECT A000045. - _R. J. Mathar_, Nov 03 2009
%e A167023 5 is in the sequence because 4=2*2 and 6=2*3. 46368 is in the sequence because 46367 = 199 * 233 and 46369 = 89 * 521.
