This must be an elementary question for the pros but how do I iterate over unique

This must be an elementary question for the pros but how do I iterate over unique triplets. E.g. 1:5 triplets would give me (1,1,1), (1,1,2), … (1,2,2), (1,2,3) … but not (1,2,1) because that combination is already covered by (1,1,2)?

You can do `unique(Set, x)` where `x` is your iterator of tuples.
