WebA (sub)group in which every element has order a power of a fixed prime p is called a p-(sub)group. Let G be an abelian torsion group.(a) G(p) is the unique maximum p-subgroup of G (that is, every p subgroup of G is contained in G(p)).(b) where the sum is over all primes p such that G(p) ≠ 0. (c) If H is another abelian torsion group, then G ... WebIn an Abelian group, every subgroup is a normal subgroup. More generally, the center of every group is a normal subgroup of that group. Every group is a normal subgroup of itself. Similarly, the trivial group is a subgroup of every group.
