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:

    The love of liberty is the love of others; the love of power is the love of ourselves.
    William Hazlitt (1778–1830)

    If nations always moved from one set of furnished rooms to another—and always into a better set—things might be easier, but the trouble is that there is no one to prepare the new rooms. The future is worse than the ocean—there is nothing there. It will be what men and circumstances make it.
    Alexander Herzen (1812–1870)
