Dear Mr. lotto tutor: can you please read my post entitled "flipper wants help from the boys" and tell me if there is a way that many lines can be formed in which 3 numbers are never repeated on any given line? It is ok to repeat 2 numbers, but to repeat 3 is a no-no. I would be interested in what you can come up with. My post of "flipper wants help from the boys " explains what I want.
