3880-4000G complete, 54000+ factors found:

http://www.sendspace.com/file/1mnh0l

It seems that about a million factors have been found since the sieve file was posted a week ago. Would removing those factors from the sieve file result in a faster sieve speed? If so, could someone upload a sieve file with those factors removed?

n=480K-485K, p=26T-27T complete, 53300 factors found: http://uwin.mine.nu/TPS/480000-48500...6T-27T.txt.bz2

Reserving p=27T-28T, same n-range.

It'll reduce the RAM requirements, but it probably won't do much else. If you're sieving, say, 1-5M for n=390000, your sieve speed will be the same as if you sieve 1-500M for n=390000.

13 may be unlucky, but it sure is better than being in last place
