[QUOTE=LaurV;461354]2*578^129468-1 is prime! (357582 decimal digits, P = 4) Time : 3685.562 sec.

I guess this kicks out this k from R578 (if not kicked out meantime, I didn't follow R578, and it wasn't reserved by me, just a lucky hit from a side project testing 2*b^n-1 for some bases b)[/QUOTE]

@Gary, k=2 of all Riesel bases are sieved by LaurV, aren't them?

Thus, you should update the reservations in [URL]http://www.noprimeleftbehind.net/crus/Riesel-conjecture-reserves.htm[/URL] (for R581, R992 (only for k=2) and R1019)

Although I don't know the sieve limit :-) )

I am not sieving, I am CLLR-ing them. Sieving is done long ago, up to n=200k and b=2048, there are right now 20 bases left, all testing in the same time, in 20 cores, currently n's between 120k and 140k. I did not make a reservation with Gary because right now I am under his limits, I started from scratch and re-checked all n's from the beginning. [STRIKE]His numbers are somewhere over 200k already, and 581, if I am not mistaken, is at 400k. I still have a lot of work until I reach these numbers, and I am not so sure I will not get bored by that time.[/STRIKE]

Mistake (I clicked your link), if the numbers there are right, then 581 is at 200k, 992 is (only) at 100k, and 1019 is at 400k. Therefore you can consider 2*992^n-1 reserved by me to 200k. Currently testing n=125676. Nothing found below, from scratch.

@Gary:
Can you check the base R1030? The sievefile containing 217 factors but 216k left, before I release the base I need to know if 1 factor was not removed from the sievefile.

Someone randomly found that 39939*1030^25030-1 is prime as shown in the top 10. Sometimes we get people searching random single k's in multi-k bases and when they find a prime I forget to remove them from already posted sieve files. That is one of the reasons that we prefer that people search entire bases instead of just 1-2 k's in a base.

k=39939 is still in the sieve file. You can just remove it. Alternatively if you have already started you can just leave it in there and you will find the above prime again.
