[QUOTE=Alfred;411244]I've lost any information an the four sequences 12012, 30450, 877552 and 930966.

I'm very thankful for any information (eg a .elf file).
The higher the index the better for me.

I only have the .elf file for 12012 till the point when I dropped it (line 2290). Hopefully factordb will start working again soon, then you will be able to download much more recent information about this and other sequences.

oops ignore this post

@Drdmitry

Line 2290 would be nice.

Factordb seems to work again. You can download much more recent .elf files from there.
