Now 205 primes

Welcome to the new searchers!

I expect that Carlos Rivera will update the puzzle page within the next day or so

In the meanwhile another prime to announce:

[B]191? 245288[/B]

this means the mooted 200th is now 414907

 robert44444uk 2013-08-08 17:37

No more primes in the 200-250K range - this is now complete.
