\emptyset is a subset of \emptyset

Explanation:

If set A is a subset of set B, then all elements in A are in B.

If B is an empty set, then it contains no elements. If A is the empty set, then it contains no elements. Because there are no elements in A that are not in B, A is a subset of B.

Hence, \emptyset is a subset of \emptyset.
