I need to know the normal subgroups of the following group G'. G' is defined as follows.
G=symmetric group on 7 elements. S=symmetric group on 5 elements, embedded in G as the subgroup stabilizing 6 and 7. R = integers mod 3. K=the free R-module with R-basis the set of right cosets of S in G. Finally G' is the semidirect product of K by G. Can anyone help?
