Power Set

In mathematics, the power set (or powerset) of any set S, written, P(S), ℘(S) or 2S, 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.

Any subset of is called a family of sets over S.

Famous quotes containing the words power and/or set:

    True freedom is to have power over oneself for everything.
    Michel de Montaigne (1533–1592)

    I consider it equal injustice to set our heart against natural pleasures and to set our heart too much on them. We should neither pursue them, nor flee them; we should accept them.
    Michel de Montaigne (1533–1592)
