Ordered Set

An ordered set - in order theory of mathematics - is an ambiguous term referring to a set that is either a partially ordered set or a totally ordered set. A set with a binary relation R on its elements that is reflexive (for all a in the set, aRa), antisymmetric (if aRb and bRa, then a = b) and transitive (if aRb and bRc, then aRc) is described as a partially ordered set or poset. If the binary relation is antisymmetric, transitive and also total (for all a and b in the set, aRb or bRa), then the set is a totally ordered set. If every non-empty subset has a least element, then the set is a well-ordered set.

In information theory, an ordered set is a non-data carrying set of bits as used in 8b/10b encoding.

Famous quotes containing the words ordered and/or set:

    The case of Andrews is really a very bad one, as appears by the record already before me. Yet before receiving this I had ordered his punishment commuted to imprisonment ... and had so telegraphed. I did this, not on any merit in the case, but because I am trying to evade the butchering business lately.
    Abraham Lincoln (1809–1865)

    It’s the set of the sails and not the gales,
    That bids them where to go.
    Ella Wheeler Wilcox (1850–1919)
