[QUOTE=10metreh;198661]Someone has used the "Set prime" feature to set [url=http://factordb.com/search.php?query=14024583629590740405696733516333578768334167843121764087477062152568441071629415220301776583483627859403452672768982350567922060593265644762694669501691625717]the c158 cofactor from 276:1635[/url] as prime.

Edit: Repair Sequence doesn't work.[/QUOTE]

Can this be fixed? The number has now been factored by RSALS so that sequence can continue.

i got that info from P.Zimmermann, too, and PM'ed Syd to correct that issue.

Andi47 2010-01-02 08:28

taking the "false prime" as starting point of an aliquot sequence and clicking "repair sequence" doesn't work.

when I enter "false prime/p60", the DB shows the p98 as a result, but still thinks that the c158 is prime...

Syd - are you still reading this thread?

Have you run the sequence further yourself? In case not, I'll see what aliqueit gives me...

another issue: submitted factors of huge numbers
 
another issue has [URL="http://www.mersenneforum.org/showthread.php?t=12939"]appeared[/URL]:

[QUOTE=Andi47;200613]Is this really a factor of 2^11550+1? The DB doesn't accept it...

Edit: these too:[/QUOTE]

[QUOTE=kar_bon;200621]try using the applet from Dario Alpern for 2^11550+1:

it shows much more factors (but not 11156048790632092546283863077521827489501, see attachment).

the FactorDB accepts other factors, but only showing them at saved results, not at the result-factorisation![/QUOTE]

[QUOTE=Andi47;200637]I just tried to take 2^11550+1 as starting point of an aliquot-sequence and then submit one of the factors - doesn't work too![/QUOTE]

[QUOTE=10metreh;200639]I tried entering that factor into the Factor box on Dario's applet and it accepted it. Maybe the DB problem is something to do with the size of the number? Or maybe it's because it hasn't proved the cofactor composite.[/QUOTE]

[QUOTE=Andi47;200643]another issue has [URL="http://www.mersenneforum.org/showthread.php?t=12939"]appeared[/URL]:[/QUOTE]
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.
