There is a Variables class (hereinafter V) with ID and Name fields. There is also a Combination Class (hereinafter C) with a SortedSet of class V objects and some other fields. And, in fact, there is a List Model

I checked them manually - they work as they should.
Can you tell me how to remove duplicates in the list?
