# Data mining: Frequent Item sets

When asked to "find all frequent Item sets" is it just the set that was last worked out that is the answer you should give or is it necessary to give all before that too.

For example, say if the last results I get for a set is (A,B,D) then is that my frequent item set or do I need to also include all found before that that also satisfy minSup, e.g., (A,B) (A,D) (B,D), etc?
