I asked: "Does any prime factor of any composite Fibonacci number with prime index appear as a prime factor for any *other* composite Fibonacci number with prime index?"
Apparently this is well known (by those who know it well). Wikipedia says: Fibonacci numbers that have a prime index do not share any common divisors greater than 1 with the preceding Fibonacci numbers.
