[quote=KEP;134372]Uhhhm, weird, guess it must have been something I've missed, well maybe you will see some repeated k's that gets primed again :smile:... it's all about the eyes I guess :smile:[/quote]

Nope, not the eyes. I plugged all your primes into Excel, used the LEFT and MID commands to get the k and n-values out of them, sorted them by k-value, and then used formulas to compare each k-value to the prior k-value. Only 3 repeated. I wouldn't trust my eyes to find the k's with more than one prime.

For top-10 prime purposes, I only consider the lowest prime for each k-value, which is why you don't see your last prime for k=368106 listed in the top 10. It has a lower prime.

Riesel Base 6
 

33627*6^66262-1 is prime!

[quote=KEP;134103]Just sent the Base 12 sierpinski to you my friend :smile: on your e-mail...

KEP![/quote]

KEP reported a status on Sierp base 12 in an Email a few days ago. He is complete to n=125.9K and as previously stated, is releasing the base.

He has now kindly forwarded his sieved file to me and there is a link to it on the Sierp reservations web page.

So we now have 2 nice sieved files on the reservations web pages:
One for Sierp base 12 for n=125.9K-250K sieved to P=3.69T and one for Riesel base 27 for n=100K-1M sieved to P=5.19T.

Thanks for forwarding the files KEP!

Reserving Sierp base 12 k=404 to n=250K

Rogue,

You had previously indicated an interest in Riesel base 27. That one is now available with a link to a well-sieved file on the reservations page.

Not for a couple weeks at least. I'll let you know when I'm ready.

I'm ready now to take Riesel base 27.

Riesel 25 update
 

Haliho everyone,

Here is an update on my Riesel 25 effort: at n = 15000, I have 337 k's left. 69 of those are also open for Riesel 5.

Willem.

Update for Riesel base 31:

Now at 75k, no more primes found :sad:

Sierp b17:
one k down, two remaining; n ~175K

Sierp b18:
one k remaining, no prime; n ~215K :(

[quote=rogue;135431]I'm ready now to take Riesel base 27.[/quote]

OK, I'll mark you down for it. Be sure and get the sieved file off of the reservations page.
