Edit: Repair Sequence doesn't work.

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

prp60 factor: 270024147888865624978340431114134748588570064023070793244919
prp98 factor: 51938257149367493435090597167989153183137693452752374632689251310926345459974978607598126301961843

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

[Andi47]

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...

Edit:

 1636 .  5553735117317933200655906472468097192260330465876218578640953073073621520345639860838715455445051384541522908567177893474300048412039606937194567203030718931558 = 2 * 3^2 * 193 * 15623882725987 * 17128057836709 * c130 = 5973904245521536952700760292305673549485551764885202615380152916870857774868021704527178046275008042710667136890273086225418063349

The c130 has had ECM to t25, P-1 to B1=5e6, B2=117870494688, and 3 x P+1 to B1=25e5, B2=46766177260.

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!

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 "PrP" rather than "Prime"....and looking at the worker status, the work queue appears frozen.
