[quote=wblipp;203154]Pascal's Odd Perfect Number search has many factors for p^q-1 that are not yet in Brent's tables nor the database. Of course even more of these factors are already in both repositories. I've manually added about a dozen missing factors to the database in the last few days, but it's tedious. Is there a way to scoop these all up?

Scooped "checkfacts.txt" into the database, by converting the txt-file to some elf-files and using "aliqueit -s" (simple c and bash script)
=>
DB reports [COLOR=Red]196784 [/COLOR]new factors!

(bit more than a dozen :smile:)

Hmm. THAT many new factors suggest that Richard Brent's factor.gz hasn't been imported, either. Does anybody know about this? It uses a format like checkfacts except that it includes +1 and -1, so each exponent includes a sign. It's at

I'm submitting it now. I'll edit or post with the number of new factors reported.
Edit: Hm, I thought it'd give it...I don't see anything here saying how many new factors the DB found:[code]Sending 278088 lines...

The file is too big, there was no transmission.

In the aliquot sequence overview page showing open end sequences,
[URL="http://www.factordb.com/search.php?so=1&se=1&start=800000&limit=100&5=1&do=Search"]http://www.factordb.com/search.php?so=1&se=1&start=800000&limit=100&5=1&do=Search[/URL]
is there a way to show the size of the last term rather than, or perhaps in addition to, the size of its unfactored part?

is the db down? i cant load it.

[QUOTE=Buzzo;204783]is the db down? i cant load it.[/QUOTE]

If it was, it isn't now.

[size=1]And even if it wasn't, it isn't now and there's nothing you can do about that.[/size]

Small database problem
 

Whenever I query the database I get a message like

select fid, status, type, digits, md from factors where smd=44863 and factor="2^941-1" - Table './fdb/factors' is marked as crashed and last (automatic?) repair failed

I am feeling rather happy to have local copies of my aliquot-sequence progress ...

Yeah, it's not just the aliquot sequences, either.

But, the good news is that it seems it is just a display and update problem. My aliperl scipt is still picking up the last lines for sequences fine. The db isn't claiming new factors, though, so I don't know if it is receiving them or not. But, like you, I have them for later.

From factordb.com:
[QUOTE]One table crashed today, repairing it right now. I'm quite sure it won't fail, but if it does, last backup ist just 12 hours old.[/QUOTE]

I hope repair will be successful.
