Maybe we should ask Jean Penne how he prefers to have them reported?

Riesel base 31
Finally, a long due result for Riesel base 31:
131994*31^681091 is prime! After a 2 months wait, it's a rather satisfying top 5000 prime too! This leaves 9 k's for Riesel base 31.

I don't believe that Jean cares, but I won't speak for him.

Interesting discussion here.
I have to lean towards what Rogue suggested despite the message in Jean's LLR program. I believe the message was put there not thinking of the ramifications of a single program pulling code from multiple sources, which as Rogue implies, gets into a very slippery slope of crediting any # of contributing programs or testers. I was not aware that each program gets full credit if more than one is used. Thanks for correcting that Anon. I was aware of the display in Jean's program but had chosen to ignore it for the same 'slippery slope' reason. If it comes back that PRP should be credited, I'll create a new proof code if I find a nonpowerof2 top5000 prime. Fortunately I haven't found a nonpowerof2 top5000 prime yet or I'd be stuck with a messy situation of moving some of them over to a new proof code, which perhaps isn't too messy for Prof. Caldwell to move a few primes over to.

BANG!!
Ba da bing...ba da boom...
The oddn conjectures finally hit pay dirt on the Riesel side and knock a kvalue out of 3 different bases... 6927*2^7434811 is prime!! This also slays k=13854 for Riesel base 4 and 16. Primes for those reported in the main prime thread. Gary

There is now one less kvalue remaining for Riesel base 4 and 16:
13854*4^3717401 is prime and 13854*16^1858701 is prime submitted as: 6927*2^7434811 Last fiddled with by gd_barnes on 20100401 at 22:23

Base 19 prime
Hidiho,
I've been taking some of my k's to much higher n's then I usually do. With success: 8216*19^910411 is prime! The only base 19 prime in the top 5000. Having fun, Willem.

Just saw this one in the log file:
160*17^166048+1 is a probable prime. Time: 4811.857 sec. Place 604 :) http://primes.utm.edu/primes/page.php?id=85139 only 2 more for sierp b17
