Elements can belong to subsets. Subsets can be elements of sets that are called "power sets".
Subsets is one type of an sets
If the set is of finite order, that is, it has a finite number of elements, n, then the number of subsets is 2n.
Venn diagrams are a means for displaying relationships between sets.
For example, if you take the set A = {1, 2}, then the following sets are all subsets of it: {}, {1}, {2}, {1, 2}. That is, all the sets that fulfill the condition that all of its elements are also elements of the set "A".
