**power set**(or powerset) of any set*S*, written [math]\displaystyle{ \mathcal{P}(S) }[/math],*P*(*S*), ℙ(*S*), ℘(*S*) or 2^{S}, is the set of all subsets of*S*, including the empty set and S itself. In axiomatic set theory (as developed, for example, in the ZFC axioms), the existence of the power set of any set is postulated by the axiom of power set.^{[1]}Any subset of [math]\displaystyle{ \mathcal{P}(S) }[/math] is called a
