Default Now 205 primes

Welcome to the new searchers!

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

http://www.primepuzzles.net/puzzles/puzz_006.htm

In the meanwhile another prime to announce:

191? 245288

this means the mooted 200th is now 414907

Didn't think I was going to get anything, but it's just like waiting for a bus - wait ages for one and two come together.
