 Mar29 comment Extensions of Abelian groups to non-Abelian groups Sorry I have a very basic knowledge in this area. I came across the cohomology and its relation to group extensions but I am looking for something more basic that I could understand. Long time ago, I remember I had seen somewhere that extensions are characterized by two mappings satisfying some conditions. Would you happen to know of a result like that?

It's interesting that the lower bound is not used in the proof. For the record, I think in your notation $n^{-1}K^n$ means $\frac{1}{n}\left(K_1+K_2+\cdots+K_n\right)$.

Dec4 comment Extension of a group homomorphism That's a very easy example, thanks! Dec4 comment Subgroups of $G^n$ Thanks Gerry, that's a very interesting post. Dec4 comment Subgroups of $G^n$ I'm interested in counting them. My motivation is coding theory in which a subgroup of $G^n$ is regarded as a code. The idea is to find a "big" collection of subgroups of $G^n$ and somehow analyze the average "coding performance" of the collection. Dec4 asked Extension of a group homomorphism Dec4 awarded Student
