yafu@home has bitten another one:

[code]11:50:36 ERROR root:42: Sequences verified as terminated:
1163160
[/code]

You collectively get one guess who found this.

I haven't bothered to figure out whose it was, but I certainly have one likely candidate in mind.

[QUOTE=ChristianB;483785]Update 1649550[/QUOTE]

Evidently he didn't stay around to watch the update, because he completed the sequence:

[code]Sequences verified as merged:

alq_880584.elf-8 . 12488816 = 2^4 * 23 * 33937
alq_880584.elf:9 . 12761056 = 2^5 * 7 * 11 * 5179
--
alq_1649550.elf-2868 . 8304560 = 2^4 * 5 * 11 * 9437
alq_1649550.elf:2869 . 12761056 = 2^5 * 7 * 11 * 5179

Yep. I didn't stay around because it was late and I knew the scripts are working fine. This is also a good example for a new feature I want to build into aliqueit. I was working on 1649550 and hit a downdriver. When the sequence turned and grew upward again I manually interrupted to upload the intermediate lines (~2300) and check for merges. And as it turned out there was a merge. So by checking with FDB I saved a lot of offline factorization time and could start the next sequence right away.
