| Nov 8, 2015 at 7:18 | comment | added | HJRW | Could you explain your definitions please? I can't come up with candidates which make your first assertion correct in the case where $A=\mathbb{Z}$ and $n=1$. | |

| Nov 7, 2015 at 8:23 | comment | added | David Carchedi | I see how both parts act. My question is how do we see this is everything? | |
| Nov 7, 2015 at 8:19 | comment | added | Qiaochu Yuan | The $\text{Aut}(A)$ part is hopefully easy to see. The other part is the translation action of $K(A, n)$ on itself. So this is at least a natural guess. In general there's always a natural action of $G \rtimes \text{Aut}(G)$ on $G$ (as a set). | |
