Let G be a group and let N\trianglelefteq G, M\trianglelefteq G be such that N \le M. I would like to know if, in general, we can identify G/M with a subgroup of G/N.
Of course the obvious way to proceed is to look for a homomorphism from G to G/N whose kernel is M, but I can't think of one.
What I actually want to show is a more specialized result (namely the case when finite G/N is the nilpotent quotient of G and G/M is a maximal p-quotient of G for some p dividing the order of G/N) but the above is a lot cleaner and didn't yield obviously to a proof or counter-example so I thought I'd explore that first.
