Looks like I just re-discovered a prime on port 2000 that was previously picked up by the Free-DC Prime Search eight years ago:

907*2^1501169-1

Does anyone know what ranges they searched in this area? My understanding is that they weren't intending to do a comprehensive search (just to find some primes), so we might be in for some hit-or-miss in the near future.

That has been an individual search by Burt not related with Free-DC drives, just the knowledge on the finding to FreeDC account.

See the first post of the 14th drive. There are only 2 more known primes after this one for k=600-1001 n=1.5M-2M. So you found a rarity.

The 13th drive has only one more known prime for k=400-600 n=1.5M-2M.

So not much hit-and-miss. :-)
