Good deal. I was worried we weren't going to find any primes with the rally.

I'm estimating that we tested ~30000 k/n pairs with the rally so would have expected ~5 primes. Finding 2 is not extremely unusual but finding zero WOULD have been!

Regardless, we knocked out quite a large chunk of work. Thanks to everyone who contributed! :smile: The participation was better than I expected on such a short notice.

I moved the discussion on the issue that we had on port 7000 to a thread called 'port 7000 issue'.
