I'm releasing R51. It had a summer break, and as I warned, I have only done a little work on it. That's why it's only at n=2800. At least it's started. :smile:

Now for the stats:

3373772 ks with primes
863253 ks with trivial factors
49593 MOBs excluded from testing
134 non-MOB ks with partial algebraic factors
29510 ks remaining

Gary, your estimate of 50000 ks remaining at n=1000 was pretty accurate. The actual figure was 49800.

I know Gary had all the data up to n=501, but in case a hard drive crashed or some similar disaster struck, I've uploaded everything to sendspace, including the primes up to n=501, instead of just sending the data past n=501 to Gary. Better safe than sorry. :smile: The file was too big to email (or at least it was too big for my email). Here is the link: [url]http://www.sendspace.com/file/veqi00[/url]
The prime file is in an odd order due to the way I computed this base and a mistake, but that shouldn't matter.

Maybe this is a base for the recommended thread (perhaps with a notice saying "Approach with caution" or something of the like)? Or maybe even a candidate for a team drive to follow S63?

Anyway, if you like a challenge, why not take this one on? :smile:

Gary, have you read this post? The pages haven't been updated yet.

[quote=10metreh;229053]Gary, have you read this post? The pages haven't been updated yet.[/quote]

Yes. I'll get to it in the near future. The large conjectures take me a little while.

Ian,

Can you give us a status on S51? Thanks.

Mixed bag. k's<1M are at n=20K - k's > 1M are at n=13K

I have approx 10K k's remaining. Slow going but I'm getting there.

Can you send me the primes? I'll act as a backup in case something happens to your machine(s).

Riesel 51 doublecheck...

10metreh,

Most everything including the algebraic factors look good.

I doublechecked this one all the way and extended it to n=3000. You did miss 18 primes, all in the n=1295 thru 1301 range or at n=1327. You might want to check your processes.

I'm not sure how you processed the range. Personally, I found it easiest to put 2 cores on it non-stop for ~12 days running the starting bases script without sieving. I ran k<=4.5M on one core and k>4.5M on the other. Sometimes for such a large-conjectured base, it's best to have the fewest human interventions possible, even if it takes a little more CPU time.

Here are the missing primes:
370020*51^1301-1
398134*51^1300-1
556042*51^1301-1
615070*51^1301-1
1091728*51^1327-1
1309868*51^1327-1
2184142*51^1300-1
2190000*51^1300-1
2534538*51^1297-1
2722070*51^1298-1
3984644*51^1297-1
4125304*51^1297-1
4511090*51^1296-1
5113084*51^1296-1
5240078*51^1296-1
6476380*51^1295-1
6569538*51^1295-1
8149010*51^1296-1


To all,

Officially for R51, there are 29,492 k's remaining at n=2800 and 28,520 k's remaining at n=3K.

All k's remaining at n=3K are shown on the R51 reservations page. I have also provided a link at the bottom of the page to a file of the k's remaining.

Mathew has indicated an interest in taking this one all the way up to n=10K. Mathew, if you are still interested, please post here. Thanks.


Gary

Perhaps these were due to the PFGW 3.3.4 bug?

[QUOTE=mdettweiler;230593]Perhaps these were due to the PFGW 3.3.4 bug?[/QUOTE]

No, all primes listed by Gary I've checked with PFGW 3.3.1, 3.3.2, 3.3.3 and 3.3.4 without any error!

But these were [i]missed[/i] primes--they weren't there to doublecheck in the first place.

I've tested them first, found as PRP and then checked prime. No errors.
