[QUOTE=schickel;200654]I think there's a problem with uploading sequences as well. I've been updating my sequences, and it seems to queue the info up, but the factors don't make it in right. Going back to a sequence after uploading some lines, the next line shows up, but each line after that takes a push of the "Quick ECM" button to make it appear. Also, some of the lines I uploaded last night still show the factors as "[COLOR="Sienna"]PrP[/COLOR]" rather than "Prime"....and looking at the worker status, the work queue appears frozen.[/QUOTE]

I have just emailed Syd about a few issues mentioned above, and I have suggested adding a "re-check primality" and/or a "repair factorization"-button.

another sequence which seems to be affected - reported factors don't show up:

[QUOTE=EdH;200748]747768: I reported my latest lines to the db this morning, but they didn't show up after two attempts. Should I wait for later or post my elf file here (or somewhere else) and move on?[/QUOTE]

Syd just answered to my mail: He is quite busy at the moment, so any updates still have to wait. But he has fixed the false prime of sequence 276 and will work to fix several broken aliquot sequences.

The factors of 2^11550+1 and such - another bug which he says that he has to fix - a factor does not get recognized if the original number is set to "unknown primality status".

The main "Report factors" box isn't working for aliquot 675600. However, submitting the factors for each line separately (in the "Submit factors" box for each number) works.

Does anyone know what the size cutoff is for factors to be displayed in "Latest Factors" on the worker status page? Somehow none of my factors seem to show up there... :ermm:

36 digits

It seems to be prime size > 35, meaning the second largest factor found.

It doesn't show if you report massive number of factors on the Report Factors page which starts with:

Factor tables: <composite> = <factor1> * <factor2> * ...
Sequences: <index> . <composite> = <factor1> * <factor2> * ...

Just my observations.

I think that if you enter the larger factor, it will show up instead of the smaller one.

[URL="http://factordb.com/search.php?se=1&aq=782880"]782880[/URL] stops at i2448 and resists to be cleaned (there's no next element). Please fix?

Done. Next time, just pick a large (>100000) factor of the number and resubmit. That'll change the status from CF to FF.

Someone has clicked "set prime" on the c163 of aliquot sequence 4788, index 2509. "Repair Sequence" doesn't fix this.

We *really* need a "re-check primality"-button.
