[QUOTE=Dubslow;308500]Sorry it took so long, I've had hardware issues and then I spent two days in Windows getting the entire summer's worth of gaming done in a few days. :razz:

That was pretty close with the ECM, though perhaps not an ECM "miss" per se. RSALS [URL="http://boinc.unsads.com/rsals/crunching.php"]reports[/URL] ECM to 3t50.

Edit: I'll do 160969_43_minus1 (it looks a bit closer to done than the one above it).[/QUOTE]Thanks for doing this one. Definitely not an ECM miss. The 2/9 rule suggests that a single t53 is enough, and even that would give an expected 30% chance of missing a p53.

This one will be in the next GCW update at [url]http://www.leyland.vispa.com/numth/factorization/cullen_woodall/cw.html[/url]

How do I merge two dat files?

The best you can do is probably to decompress the large file to a new file, and decompress the small file while appending the contents to the new file.
If msieve took relations in bzip2 format, you could decompress the small file and recompress it with (p)bzip2, then append the compressed file to the large file.
