Dear Rhino Community,

I would like to create several distinct sets of indices (to select polygons). By changing the seed of “Random Reduce” I want to obtain several sets where:

- there are no repetitive indices within each set.

For instance, this set (1,4,1) is not correct because there are two times “1”

**AND**

- Each scenario is unique (hence the position of the indices in the list does not matter) For instance the sets (1,5,2) and (2,1,5) should be considered as the same set and should appear only once in the final list

I have used Jitter and Random Reduce. The first condition (no repetitive indices) has been already included in the model. I don’t know if it’s possible to manage the 2nd condition (distinct scenario).
