SUMMARY
The power set of the empty set, denoted as P(∅), is defined as {{}}. This means it contains only one subset, which is the empty set itself. The discussion clarifies that while the set {∅, {∅}} has two members, its power set contains four subsets: {}, {∅}, {{∅}}, and {∅, {∅}}. This establishes that the power set of the empty set is indeed a foundational concept in set theory.
