Yes subsets is related to supersets

If A and B are sets and every element of A is also an element of B, then:

• A is a subset of (or is included in) B, denoted by ,

• B is a superset of (or includes) A, denoted by 

If A is a subset of B, but A is not equal to B (i.e. there exists at least one element of B not contained in A), then

• A is also a proper (or strict) subset of B; this is written as 

• B is a proper superset of A; this is written as 

For any set S, the inclusion relation ⊆ is a partial order on the set  of all subsets of S(the power set of S).
