1. The problem statement, all variables and given/known data Here's the problem. We define the triple primes as triples of natural numbers (n,n+2,n+4) for which all three entries are prime. How many triple primes are there? (Hint:mod 3.) (By way of contrast, it is not yet known whether the twin primes-that is, pairs (n,n+2) with both entries prime-form an infinite collection.) 2. Relevant equations see above 3. The attempt at a solution i'm stuck in this problem, don't know where to begin.
