Note that k=733 has been searched to 5M in 2015/2016.

Still have the LLR residues of it. In rieselprime i see it listed under nplb drive14 (MR3).

Can you provide links to the postings where this testing was done? Alternatively posting the residues would be sufficient.

That will give us the best history for updating the Wiki.

NPLB tests all k's in the k=301-1001 range so k=733 becomes a double-check.

Yes - as you can see from my 2015 posting. I took k=733 then and tested it until into 2016. Just have been checking on my computer. Seems a couple of hundreds weren't run yet (nearby 5M). Finishing those at a handful of cores now.

All other residues are there it seems. Where can i upload them to?

I see this posting where you reserved it:
https://mersenneforum.org/showpost.p...&postcount=293

I don't see any posts where you gave status reports. Were there any? We will update the Wiki to show the whole history.

When you are done with your testing you can attach a file of residues to a posting here. It's a low-weight k so I think a zipped version of the file will be within the site's attachment size requirement.

No worries - i'll give a status update when it finished 5M.

diep · 2021-10-17, 22:30

k=32767 - searched to 7M. continuing (sieved it to 30M and will continue sieving it further as removal rate still was ok though electricity costs $$$ - will fire up box in office in winter as office may not drop under 15 celcius for equipment and epoxies and other stuff here, very accurate bearings huh and gas price is becoming 1.30 euro a m^3 now for heating so better use electricity!)

With LLR 3.8.23 gwnum 29.8 i've had quite some errors (which then trigger of course a fft-size increase) searching it. Not very happy about those errors. Intend to test out LLR2 here a little and will decide whether i give it a shot at it later on. With the gerbicz turned on of course if it has it.

He began sieving/testing at n=5M. So n=5M-7M is complete and there is a testing gap for n=1M-5M for this k.

Why do you post this nonsense? I said searched 'until' 7m.
Of course i started at zero there.

My apologies.

The post that I linked to gave the impression that you only sieved n=5M-30M. I will delete it.

Aha i see - your Ingliz understanding is not so 'great'.

"right now" in that old posting means the break even point shifted.

So after initial sieving of [2m - 30m] as i had already tested up until 2m with a small sieve - the break even point shifted for testing versus sieving. So i started testing until 4m and then sieved [4m - 30m]. Then when break even point shifted again - i started testing 4m-5m and started sieving 5m-30m.

Right now would still continue sieving [7m-30m] because the machine that would sieve when it is cold here, it's not so fast in testing.

We would like to reserve k=23 from n=5,000,000 under "Underwood et al"

Happy5214 · 2021-11-03, 02:52

(Note to mods: still not clear if this is the right thread. Please confirm.)

As of November 1, the (near-)Woodall k's listed in https://www.mersenneforum.org/showpo...&postcount=363 have been completed to n=575k. Four primes were found. I'll just dump them in a code block since I don't feel like creating a symlink with the txt extension.

Code:

1183953 555344
1183953 559022
8508301 567213
