If H ≤ G, then the operation induced on left cosets of H by the operation of G is well defined if and only if any one of the following conditions is true: H is a normal subgroup of G. If h ∈ H, a ∈ G, then there exists h ′ ∈ H such that h ∗ a = a ∗ h ′. If h ∈ H, a ∈ G, then a − 1 ∗ h ∗ a ∈ H. Proof. WebAll members of a coset therefore appear on an equal footing, so that any member of the coset can be taken as the “coset representative” that labels the coset and from which the coset can be constructed. For example, for the right coset {C 4y, C 2d} of the point group D 4, the coset representatives could equally well be chosen to be C 4y or ...
