4: Subgroups
( \newcommand{\kernel}{\mathrm{null}\,}\)
- 4.1: Introduction to Subgroups
- Sometimes groups are too complicated to understand directly. One method that can be used to identify a group's structure is to study its subgroups.
- 4.2: Subgroup Proofs and Lattices
- Using Lemma 4.1.1 and the argument preceding it, we have the subgroup proofs and lattices in this section.
- 4.3: Exercises
- This page contains the exercises for Chapter 4.
