Homework Help Overview

The discussion revolves around the properties of maximal subgroups within the symmetric group S3, specifically questioning whether the subgroup generated by the transposition (12) is maximal.

Discussion Character

  • Conceptual clarification, Assumption checking

Approaches and Questions Raised

  • Participants explore the definition of maximal subgroups and question the validity of a statement regarding subgroup containment and group products.

Discussion Status

Some participants have provided counterexamples and expressed uncertainty about the implications of their findings. There is an ongoing exploration of the properties of S3 and its subgroups.

Contextual Notes

Participants are considering the implications of subgroup relationships and the definitions of maximality within the context of finite groups.

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?
 
I tried, but I failed. Thanks.
 
What could go wrong??
 
S_{3}, <(12)> maximal, <(23)>, S_{3} not equal <(12)><(23)>
Thank you very much.
