NettetWhen we prove Lagrange’s theorem, which says that if G is finite and H is a subgroup then the order of H divides that of G, our strategy will be to prove that you get exactly this kind of decomposition of G into a disjoint union of cosets of H. Example 4.9 The 3 -cycle (1, 2, 3) ∈ S3 has order 3, so H = (1, 2, 3) is equal to {e, (1, 2, 3 ...

Let G be the additive group of the integers, Z = ({..., −2, −1, 0, 1, 2, ...}, +) and H the subgroup (3Z, +) = ({..., −6, −3, 0, 3, 6, ...}, +). Then the cosets of H in G are the three sets 3Z, 3Z + 1, and 3Z + 2, where 3Z + a = {..., −6 + a, −3 + a, a, 3 + a, 6 + a, ...}. These three sets partition the set Z, so there are no other right cosets of H. Due to the commutivity of addition H + 1 = 1 + H and H + 2 = 2 + H. That is, every left coset of H is also a right coset, so H is a normal subgroup.
