It is the set comprising the following 4 elements:phi,{phi},{{phi}} and{phi, {phi}}
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 ∅.

No. If the cardinality of a finite set is N, then that of its power set is 2N. These cannot be equal for any non-negative integer N.
The cardinality (size) of the power set of a set with n elements is 2n.

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

That's the set of all subsets of a given set.
Any power set out in a corporation's bylaws is ultra vires.
The power set of the empty has one member, which is the set whose member is the empty set . {phi} ( Actually the symbol for the empty set is the Norwegian letter O which resembles the Greek letter phi but is a different symbol )
No, but it is a subset of every set.It is an element of the power set of every set.
