Hall subgroup - Wikipedia
Hall's theorem. Hall (1928) proved that if G is a finite solvable group and π is any set of primes, then G has a Hall π-subgroup, and any two Hall π-subgroups are conjugate. Moreover, any subgroup whose order is a product of primes in π is contained in some Hall π-subgroup. This result can be thought of as a generalization of Sylow's ...

The union of subgroups is not necessarily a subgroup, but the intersection of subgroups is always a subgroup. Before I prove this, a word about notation.

What is the difference between a Subgroup and a subset?
A subgroup is a subset which is also a group of its own, in a way compatible with the original group structure. But not every subset is a subgroup.

group theory - What exactly a proper subgroup means? - Mathematics ...
$\begingroup$ Some authors want $\{e\}$ not to be a proper subgroup, others are fine with it (possibly) being proper. There's not much you can do about your current situation other than deal with the fact that Galian's book doesn't agree with the convention that some of your teachers use: the practical way would be knowing which convention each of your teachers uses. $\endgroup$

Subgroup series
In mathematics, specifically group theory, a subgroup series of a group is a chain of subgroups:
where is the trivial subgroup. A subgroup series is used in the subgroup method.
Subgroup series are a special example of the use of filtrations in abstract algebra.

CEP subgroup
Equivalently, every normal subgroup of the subgroup arises as the intersection with the subgroup of a normal subgroup of the whole group. In symbols, a subgroup is a CEP subgroup in a group if every normal subgroup of can be realized as where is normal in .
