Excitement: 201 254039 is prime.
Disappointment: This had been found Aug 2005 by someone else not involved with 15k.
So it gets added to k<300 stats page, but not to our ownership of the top5000 list.

Yeah, I missed that one, but it's just a book-keeping miss since on our list k=201 is marked as tested to n=250k. But it's still a disappointment for you, sorry about that. :sad: BTW, the person who found it is with the PrimeSearch project and he checked k=201 to n=260k.

The prime is now on the [URL="http://www.15k.org/riesellist.htm"]list[/URL], together with the latest primes from the 2nd Drive found by Thomas and Larry.
