Definition: Suppose G is a group, and H a normal subgroup of G. The group consisting of the set G/H with operation defined by (aH (bH) (ab) is called the quotient group of G by H.

Definition: Suppose G is a group, and H a normal subgroup of G. The group consisting of the set G/H with
operation defined by (aH (bH) (ab) is called the quotient group of G by H. (Sometime the ter factor
group" is used in place of "quotient group".)

a, be G, ф(a
b)-ф(a)od(b).
Definition: We say that groups are isomorphic if there exists an isomorphism between them. If G and H are
isomorphic groups, we write in symbols GH
