In many of the examples that we have investigated up to this point, there exist other subgroups besides the trivial and improper subgroups. Example 3.24 In mathematics, more specifically in abstract algebra, the commutator subgroup or derived subgroup of a group is the subgroup generated by all the commutators of the group. The commutator subgroup is important because it is the smallest normal subgroup such that the quotient group of the original group by this subgroup is abelian.
