Riesel base 308
 

Hi folks,

I've run the numbers on Riesel base 308. There are 7 k's left at n = 25,000:
7*308^n-1
43*308^n-1
52*308^n-1
59*308^n-1
67*308^n-1
74*308^n-1
89*308^n-1

Regards, Willem.

Riesel base 492
 

Hi folks,

I've run the numbers on Riesel base 492. There is one k remaining at n = 25,000:
23*492^n-1.

Cheers, Willem.

Riesel base 473
 

Primes found:

2*473^660-1
4*473^13-1
6*473^1-1
8*473^200-1
10*473^1-1
12*473^48-1

With a conjectured k of 14, this conjecture is proven.

The conjecture is k=104 and you show it as k=101 with primes up to k=100. I'll hold off on showing anything on the pages other than a reservation until I get them all.

Once again, it would really help if you would simply attach the pl_primes.txt, pfgw-primes.log, or pfgw.log file to your posting. I have processes in place to sort them by n-value for posting on the pages. For these keyed in sheets, I have to do manual manipulation to get them in the order that I need plus do a primality check on them since they are not coming directly from any software that I am aware of.

If they are on a remote machine, one of the 2 above files can be Emailed to yourself or to me. That's what I do when I'm out of town and have to copy a file from one computer to another. I can do that using a free remote access service.


Thank you,
Gary

You have the conjecture at k=59. It is actually k=86. Many primes are missing. Please rerun. I'll show it as reserved by you to n=25K.

One more thing: Both of these were posted in the base 101-250 thread and I had to move them. Please make sure they are in the correct thread. Thanks.

Argh, for some reason when I picked up the conjectures I mangled a few. I knew about the 308 equals 104, but manage to post the old version.

Sorry for the trouble, I'll go about and repair it.

Willem.

New bases S335 and S440 k=8 conjectures are complete to n=25K.

Only k=4 remains on both of them.

Riesel base 333, k=502
Remaining k's:
14*333^n-1
16*333^n-1
302*333^n-1

Trivially factors: k=84,250,416

Base completed to 25K and released, primes attached.

Riesel base 362
 

Primes found:

2*362^4-1
3*362^15-1
4*362^1-1
5*362^2-1
6*362^26-1
8*362^28-1
9*362^1-1

k=7 remains. This has been tested to n=25000 and is being released.
