In abstract algebra, a normal subgroup is a subgroup which is invariant under conjugation by members of the group of which it is a part. In other words, a subgroup H of a group G is normal in G if and only if gH = Hg for all g in G, i.e., the sets of left and right cosets coincide.Normal subgroups (and only normal subgroups) can be used to construct quotient groups from a given group.n other words, a subgroup H of a group G is normal in G if and only if gH = Hg for all g in G, i.e., the sets of left and right cosets coincide.
In mathematics, a group is an algebraic structure consisting of a set of elements together with an operation that combines any two elements to form a third element.The operation satisfies four conditions called the group axioms, namely closure, associativity, identity and invertibility.nformally, a subgroup is a group H contained within a bigger one, G. Concretely, the identity element of G is contained in H, and whenever h 1 and h 2 are in H, then so are h1 â¢ h2 and h 1 â1, so the elements of H, equipped with the group operation on G restricted to H, indeed form a group.
