Homework Help: Maximal subgroup of a group

  1. Dec 7, 2011 #1
    If G is a finite group and M is a maximal subgroup, H is a subgroup of G not contained in M. Then G=HM.

    Is this true?

    No. Can you find a counterexample?

    S_{3}, <(12)> maximal, <(23)>, S_{3} not equal <(12)><(23)>
    Thank you very much.
