Well, as a school project, we had to pair up and find any set of numbers other than counting numbers that would go on indefinitely. So we put on a paper all them up to a 1000 on a poster as a background for our presentation. There are actually some definite rules to finding the next one form any other prime number that we found out about which are pretty neat. So I should be able to keep going for awhile.

Either 747 or 751?
I had a pattern, but it fell apart after 700.
You guys are quite impressive!

Yep, 751 is after 743.

And then for mine, 757.
