A prime nonuplet (Posted on 2017-12-27) Difficulty: 2 of 5
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?

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.
