PRP+proof support came with v30 and that was released Aug/Sep 2020, the quoted examples all had their PRP done in May/Jun 2020.

I have also noticed that exponents that I submitted are still reserved. This happened saturday, UTC 15:47.

You must think bigger ;) The limit is around 10k at once, last time I have reported around 170k results without any problems. At this time I can only report around 1.5k results before the server is running into the ressource error. Its very slow at the moment. I had around 70k results which were already reported but still assigned yesterday. I sent a PM to prime95 to take a look.


If someone has a script which is reporting line by line from a results file that would be great. Thx everyone, looking forward...

I noticed that all PRP results for cofactors are now marked as "Factored" regardless of whether or not a factor has been found.

Can you provide a specific example please?

Pretty much all of them. Even prime cofactors are marked as "verified." I've attached a screenshot as an example.

Your example (M57131) is apparently certified P17152 in addition to those 4 factors, so I'm not sure what part you're objecting to. Perhaps re-explain this for me?


The thing I do find odd with this exponent is the result from Squeeky_Squirrel on 2017-12-31 as a PRP claimed on only 1 cofactor. Moreover, the history for the exponent doesn't list this test so I can't see that in more detail (and also the result won't show up on mersenne.ca since the export data is from the history log). Perhaps George or Aaron can poke around in the database and make some sense of this? My best guess is that the second run uses the composite of the small known factors as the supplied cofactor and primenet didn't (at the time, it does now) check that the supplied cofactor was prime.

Perhaps the composite 4-factor was used as a whole, not as 4 factors after the assignments.

It's my understanding that a primality test is marked as "factored" if the a factor is found for the exponent or cofactor. In this particular example, the cofactor is prime and should not have any factors. Yet it's still marked as "factored" even where all other four factors are accounted for. This was not the case until recent months.
