The power set of a set, S, is the set containing all subsets of S - including S, itself, and the null set.

The power set of a set, S, is the set containing all subsets of S - including S, itself, and the null set.
If tiu have a set S, its power set is the set of all subsets of S (including the null set and itself).
To me, I believe that a power set is not empty. Here is my thought: ∅ ∊ P(A) where P(A) is the power set and A is the set. This implies: ∅ ⊆ A This means that A = ∅, but ∅ ∉ A. ∅ ∊ A if A = {∅} [It makes sense that ∅ ∊ {∅}]. Then, {∅} ⊆ A, so {∅} ∊ P(A) = {∅, {∅}}. That P(A) is not empty since it contains {∅} and ∅.
