EXAMPLE
|
The Fibonacci numbers (A000045) start 0,1,1,2,3,5,8,13,21,..., so the first 1 is a term here, but the second 1 is not. (Note that 0 has infinitely many prime divisors.)
21 = 3 * 7 and 34 = 2 * 17 both have two prime factors, and because they are contiguous in the Fibonacci sequence, 21 is included.
