Hi fivemack,

Welcome to RPS!

Thanks for the greeting! I'm using two cores of a core2/2.67GHz at the office, so about 3000 seconds per exponent - my farm at home is devoted to NFS factoring of smaller numbers. I can't guarantee that I'll be on this project for very long, but felt I ought to look for some primes at some point.

1664-1666 complete (and, thanks to a mistake in splitting the files, even double-checked some of the exponents!). No primes. The person whose machine I'm using is coming back tomorrow, so I won't reserve anything more for the moment.
