I have a list of items that looks like this :
The goal would be to get every unique combination of 4 of those items.
The combinations are unordered so ABCD, BADC, DBAC, etc. are considered the same result and only one of them should appear.
With this example, the result should look like this :
With only 5 items it's quite easy to calculate in your head, but my real project has 18 of those items, which means there is 3060 combinations ...
The ideal output would be 1 item per column but this isn't that important as I can still separate them later if needed.
I don't mind having to setup a new sheet only for the calculations.
