WebbDefinition-Power Set. The set of all subsets of A is called the power set of A, denoted P(A). Since a power set itself is a set, we need to use a pair of left and right curly braces (set brackets) to enclose all its elements. Its elements are themselves sets, each of which requires its own pair of left and right curly braces.
