Simple Group

In mathematics, a simple group is a nontrivial group whose only normal subgroups are the trivial group and the group itself. A group that is not simple can be broken into two smaller groups, a normal subgroup and the quotient group, and the process can be repeated. If the group is finite, then eventually one arrives at uniquely determined simple groups by the Jordan–Hölder theorem.

Famous quotes containing the words simple and/or group:

    The first man, who after enclosing a piece of ground, took it into his head to say, this is mine, and found people simple enough to believe him, was the real founder of civil society.
    Jean-Jacques Rousseau (1712–1778)

    We begin with friendships, and all our youth is a reconnoitering and recruiting of the holy fraternity they shall combine for the salvation of men. But so the remoter stars seem a nebula of united light, yet there is no group which a telescope will not resolve; and the dearest friends are separated by impassable gulfs.
    Ralph Waldo Emerson (1803–1882)
