I'm going to assume here that it happened while the composite was small? If so, there are some numbers in the 20-25 digit range that msieve has problems with. Do you also have yafu installed? If so, aliqueit will switch over to yafu, which can usually factor the composite when msieve can't.

And welcome back!

That means that yafu has failed to factor a number. This generally happens with small composites like c25 which were split off by P-1. When this happens, aliqueit calls msieve instead. If msieve fails too, you will get WARNING: couldn't find factor in msieve.log and aliqueit will run into an endless loop. In this case, find the composite in aliqueit.log and split it separately with ECM. Then restart aliqueit with the extra switch -f <one_of_the_factors>.

Also, you don't need to post your .elf files. Just submit them to factordb.com by running aliqueit <the_sequence> -s 0.

I'm going to try a truly automated run overnight, so I'll take all of
765624, 765732, 765864,
767296, 767520, 767550, 767640, 767802,
768042

I made a download that includes the elf or alq files for all open aliquot sequences. The elf files had a program run over it that removes the 'shorthand' values (ones with +,*,^,#,!, etc on the left side of the equation). Also the final partial line is gone as this causes issues in windows.

You can find it posted below under 'All the open aliquot sequences'. It is current as of Jan 11, 2009. It also includes at least part of the two 'broken' sequences in the database - 417336 and 749320 from a previous download.

Note that it is post #14 that has the up to date ones.

I thought that bug had been fixed - I only get a "WARNING: @index ***: partial last line. Resuming..." message and then things proceed as normal.

BTW, how is 770k-780k getting on?

For windows, it doesn't correctly put in a new line so you get two indices on the same line. So it does continue, but you have to go back and add the newline in or the db is missing one index. I am pretty sure this wasn't ever fixed.

It is my understanding that everything works for unix.
