Having looked at the solution again, it's nearly completed, we can see the different sets actually have not been sorted and put together ie. EquivalenceClass( A, 3 ); [{a[1] + a[2] + a[3]}, [2, 1, 2, 1]], [{a[1] + a[2] + a[4]}, [2, 2, 1, 1]], {a[1] + a[3] + a[4]}, [1, 1, 2, 2]], [{a[2] + a[3] + a[4]}, [1, 2, 1, 2]] all these sets have the same set of values but have been put into different sets as they haven't been sorted.

That's a great solution thank you, but i would like to further it not to just solutions of just the sum of two but also to all possible subsets. So in my example i used subsets of size two but i would also would like subsets of size three for example, The actual problem I'm working with is fairly large and will require much larger subsets. I will also try my best to work on a solution as well, however i'm fairly new to using Maple and any help is much appreciated.

that is exactly what i wanted thank you, I just needed to analyse some numbers but they were getting too large so i reverted to Maple for some help, thank you very much

Thank you both very much for the help it is much appreciated

Thank you very much with your help, when i try using this i get "Error, reserved word `return` unexpected" Is there a simple fix that i'm missing?
