Since the list is quiet...
Does a Fibonnacci series contain a finite or an infinite number of primes?
From what I understand..
In a gen.F sequence if the first two numbers are divisible by a prime all
its numbers are divisible by the same prime, if

Hi folks
U(1) = 1786772701928802632268715130455793
U(2) = 1059683225053915111058165141686995
U(N+2) = U(N+1) + U(N)
I checked a few thousand terms, and they were all composite.
There is almost certainly a 'covering set' of divisors. In essence you need
to find a set of primes P and a modulus M,
