Quote (Joe G @ Oct. 14 2012,20:54)  Quote (olegt @ Oct. 14 2012,20:52)  Oh, and Joe thinks he knows what a superset is, even though his understanding differs from the commonly accepted mathematical definition.
Let's hear from him directly, ladies and gentlemen.
Joe, here is a set: A = {1,2,3}. Anyone knows that {1}, {2}, and {3} are subsets of A. Is {1,2} a superset? 
There is only one superset in a nested hierarchy, ie only one set that consists of and contains ALL other sets.
Now you may take issue to that usage but that is your problem, not mine.
The fact remains in a nested hierarchy there is only one set that consists of and conatins ALL of the other (sub)sets. So that would be "the" superset. Duh. 
This is reminiscent of the time that Joe couldn't understand that the empty set is a subset of every set.
In any case, Joe, take it from our long and varied experience, it's best to simply admit your error and learn. We have acquired quite an education thereby.
