I want to find out all the different combinations of 16 different sets.
Exactly how are these "combinations" formed?
It seems that we have 16 objects.
Are we taking them one at a time, then two at a time, then three at a time, etc. ?
For example here is what my set looks like:
Just what is this set?
Are there two objects in the set ... both of them "a-b"?
Is that really a subtraction?
We might be able to help if you gave us the original problem.
