If you also need all combinations of the order of the data involved, then you can use a Permutation component:

Permutation Component (generic indices)

OK, so I often need to try out all combinations of things and so I implemented a Permutation Component which takes any list with any type of data items, and based on the size of the input list, produces a new list of indices (integers) with all the possible combinations (output PIndices). These indices can be used to “scramble” also the input data into all the same possible combinations, or let the component do the job for you directly by tapping the PData output. In case someone else also have…
