Ah that vaguly looks familar (high school was a long time ago). Now I don't think it can be applied to this series as part of the definition says "where no two xj are the same." Or am I misssing something?

    Yes, you are missing something :-)
    In this case, the x's are 1,2,3,4,5,...,n and the y's are 2,2,2,3,7,...m
