Looks like not just those.....I was looking at the list of unfactored composites and found this one:

 FF 21 (show) 476006172212715945491<21> = 49974229

That should actually be:

476006172212715945491 = 520763 (Curve 1) x 18290533 (Curve 1) x 49974229

Maybe a missing index?

I've probably found 4-5 of these just browsing around in the last 15 minutes. The gremlins are out in force.

Looks fine now. Perhaps whatever the problem was has since been resolved?

I've had a problem uploading Primo certs or getting a batch of PRPs to work on.

Uploading a zip file gives "0 certificates found, 0 certificates added." Trying to download a new batch of input files gives the source of the download page, but with a .zip extension....

[Edit: Whups, it's actually totally broken.....uploading a single cert gives an error: "Not a PRIMO certificate"]

I had that same message when I tried to upload a .cr file instead of a .out file

Another of those intermittent problems. The certs loaded fine just now....(and I got some more PRPs to chew on.)

How do I use wget to retrieve a clean elf file without leading and trailing garbage?

 wget "http://factordb.com/elf.php?seq=159978" -O Test159978.elf

or

 wget "http://factordb.com/elf.php?seq=159978&type=1" -O Test159978.elf

or, several other things I've tried, including the older search.php versions...

...best result for any attempts:

I can write a filter to remove the trash, but I would rather not have to.

Here's an example for sequence 4788:

wget "http://factordb.com/search.php?se=1&aq=4788&action
=last&text=Text&raw=1" -q -O alq_4788.elf

That works, or you can use the format of the "Download .elf file" link from the sequence page:

http://factordb.com/elf.php?seq=4788&type=1

Thanks, but that's what I used to use before the db upgrade and it's also one of the search.php references from my previous post. Does this actually work correctly for you guys, or do you filter out the garbage somewhere? I get the following on several WinXP, Fedora and Ubuntu machines, using your exact example (minus the crlf):

0 .   4788 = 2^2 * 3^2 * 7 * 19

Is it possible that only "I" am having this issue? It's showing up across platforms. It would have to be a pretty selective occurrence to only hit me, but still hit all my machines - ISP specific, I suppose.

The Download link is fine for manual retrieval, but it's useless for my AliWin program or the AliPerl script.
