i have list of numbers for example 1,3,5,7,9 i want to add them in all possible permutations such that i get 1+3, 1+5, 1+7, 1+9, 3+5, 3+7, 3+9, 5+7, 5+9 and 7+9
Thanks A lot Alex, I had simplified the the problem. I have list of random numbers (areas of rooms). However, i worked it out just now :-)...using cross reference - lower triangle strict.
