a 27 digit twin prime pair
I found this pair of 27 digit twin primes:
1- 149907114776274341482621993 2- 149907114776274341482621991 I would know if it is possible with Pari or Pfgw to find the next and the previous pair of twin primes? |

Yes, it is possible, and it takes less than a second to run.
Code:
gp > n=149907114776274341482621993; while((m=nextprime(n+1))-n>2, n=m); n %1 = 149907114776274341482622207 The other direction exercise for you. |
