It need time to get all the info. It is now listed as a TF find

[QUOTE=Flaukrotist;561464]I wonder why for [URL="https://www.mersenne.ca/exponent/102796261"]M102796261[/URL] the found factor is displayed under the factors section but not in the Trial Factoring Results table together with the entry for 75-76 bits like e.g. for [URL="https://www.mersenne.ca/exponent/111954527"]M111954527[/URL].[/QUOTE]It does, you're just not seeing it.

I'll guess that you looked at the exponent page immediately (at least same day) after having found the factor. Newly-discovered factors are added to the database every hour (from the [URL="https://www.mersenne.org/report_recent_cleared/"]Recently Cleared[/URL] list), but details about who-did-what-when only get imported overnight (~1-2am UTC). The exponent pages at mersenne.ca are heavily cached, so if you're not seeing it in your browser, try Ctrl-F5 to forcibly-refresh the page and the result should show up for you.

Thanks for the explanation. That might very well have happened in the way you described. :davieddy: Now it is also displayed for me.

[url=https://www.mersenneforum.org/showthread.php?t=26188]mersenne.ca server migration and probable downtime (Nov 2020)[/url]

There is some unexpected data in the nightly PrimeNet export, waiting for Aaron to fix, stats and such will be delayed.

edit: Fixed now.

Putting the site in the short-term suspended state while I apply a database change. Should only be a few minutes (... I think)
edit: and we should be back.

For those who use the [url=https://www.mersenne.ca/pm1_worst.php]Worst P-1[/url] tool, the calculations have changed. Previously the P-1 probability was calculated as being done after the TF which has been done on the exponent. The problem with this is that if an exponent has had abnormally-high TF then the apparent probability for the P-1 drops very low, even though it was done to reasonable bounds. The new calculation is done as assuming TF was done to GIMPS-standard, which makes it easier to find P-1 that was actually badly-done and should no longer falsely report an exponent is a candidate for a better P-1 when the first P-1 run was fine but also had very-high TF.

This will mostly affect the lowest exponents that have had considerable factoring effort of all types, but it will also impact the "expected" values for what makes a good P-1 or not. As a rough approximation, where you say 2% before would be a rough analog to 5% in the new system.

and, another trouble.
the k of my most recent P-1 isn't calculated/displayed correctly

[QUOTE=firejuggler;564983]and, another trouble.
the k of my most recent P-1 isn't calculated/displayed correctly[/QUOTE]Thanks, there's something weird going on with my factorization routine, investigating...

[QUOTE=firejuggler;564983]the k of my most recent P-1 isn't calculated/displayed correctly[/QUOTE]Thanks, that was an important bug to uncover. I had merged two factoring routines that I thought were compatible, but they treated the results slightly differently so basically everything passed to it came back "prime". I believe I have found and fixed the problem, and the upside of the recent downtime is that fixing those values that were incorrectly flagged as prime is pretty straightforward. It took a little time to walk through them all (10231 records), but they should all now be fixed.
edit: fixed another 876 rows that were broken differently.

It is still problematic: [URL="http://www.mersenne.ca/exponent/10667659"]http://www.mersenne.ca/exponent/10667659[/URL]

The first factor's k is unfactored, B1 and B2 are wrong (even if k was prime).

Edit 1: What's up with [URL="http://www.mersenne.ca/exponent/23509"]http://www.mersenne.ca/exponent/23509[/URL]? Shouldn't it be B1=563 and B2=7[SUP]4[/SUP]=2,401? Or am I misunderstanding P-1 bounds here?

Edit 2: Just did Ctrl+F5. It got worse and removed factorizations of every k. I chose the above two exponents because I was quite sure I have not opened them before, so it's most likely a script that changed?
