WOOOHOO, birthday prime, found yesterday :)
262*17^186768+1 is a probable prime. Time: 7393.195 sec. http://primes.utm.edu/primes/page.php?id=85256 only one more to go!

OH YEAH!! A harty congrats from all at CRUS! We'll have to call you the base 17 slayer! That's remarkable to find two primes so close together for such a high base at such a high nrange! Gary

Congrats on the Base 17 Xentar, and to you too Gary on your 2 Base 256 primes...

Finally, after more then 2 month waiting:
74924*31^813811 is prime! (121374 digits, around nr. 2725 in the top5000) This now leaves only 8 k's to go for riesel base 31. Last fiddled with by michaf on 20080725 at 17:33 Reason: top5000 entry

After a very long dry spell for the 40 k's remaining on Riesel base 256, it finally scores its first top5000 prime:
7179*256^665851 is prime submitted as: 7179*2^5326801 All k's on Riesel base 256 are at n=67K; still going to n=75K. Gary Last fiddled with by gd_barnes on 20081113 at 11:00

for the LiskovetsGallot conjectures:
Riesel odd n: 106377*2^4755691 is prime 9 to go!

prime riesel base 48
Bingo!
7127*48^784071 is prime with 131825 digits. It comes in at place 2505 in the top 5000 list. I still need 5 more primes to prove the conjecture for prime riesel conjecture for base 48, so chances are that proving it is out of reach for now. Cheers, Willem.
