I would like to get it so that duplicates like david - dianne and dianne - david were elminated so for say a list of three names: david dianne phillip I would only end up with 3 pairs david dianne david phillip dianne phillip ---------------------------------- This code removes the permutations that you mentioned and should yield the results you want. items > results 0 > 0 1 > 0 2 > 1 3 > 3 4 > 6 5 > 10 etc [Non-text portions of this message have been removed]
