- A quadruplet of primes occurs when four out of five consecutive odd numbers
- are prime. Except for the first two quadruplets, 3,5,7,11 and 5,7,11,13,
- all quadruplets of primes are of the form 30n + 11, 30n + 13, 30n + 17,
- 30n + 19. It is well known that there are only finitely many prime
- quadruplets.
- Question 1. Is the largest prime quadruplet known?
- Question 2. If not, what is the largest known prime quadruplet?
- Question 3. Up to which n (see above) are all prime quadruplets known?
