I am attempting to describe a relationship between a set of sets S and a subset of S, T, as follows:
$$T = \{ x | x ∈ S \land \forall y(y \in S ⇒ y \not\subset x) \}$$
As I understand, this means T is a subset of S containing all sets of which no other members of S are strict subsets.
Is there a mathematical term that describes this relationship?
