S315
I may as well post my find for today. It gives us 3 nice ones in a about a day.
1390*315^101935+1 is prime but NOT Top5000 278*315^180134+1 is prime and IS Top 5000 http://primes.utm.edu/primes/page.php?id=119998 All k's for S315 tested to 180K and continuing. This makes S315 a 2ker Gary: Sorry for not posting the smaller one. I was waiting until I reached n=200K but the big one showed up. Last fiddled with by MyDogBuster on 2015-06-13 at 12:59 |
