INTERSECT ?

[1,2,3,2] intersect [0,2,3,2] -> set[2,3]
There is no duplicate with intersect.
The history displays intersect incorrectly prefixed in 2d mode, but correctly in algebraic mode.

Details that are leaving overlook. Also to avoid misunderstandings the history-view on CAS mode must be different than in HOME mode, using real symbols of sets, I think it is not difficult to implement, as they see are many hours of coding, but a more precise mathematical system
