p is a 4-digit prime number. p+30 is also prime. There are 9 primes from p to p+30 inclusive. What is p? What are the 9 primes in the nonuplet?
(In reply to
computer solution (spoiler) by Charlie)
This seems like a remarkably tight cluster of primes (Is 9 primes from P to P+30 the most possible?)
Differences from 1277
+2,6,10,12,18,22,24,30
Consecutive gap sizes
2,4,6,2,6,4,2,4
3 pairs of twin primes.
3 pairs that differ by 4.
5 pairs that differ by 6.
