$op_1$ is (name of property): $axiom_1$
nilpotent: if $Z_0=\{1\}$ and $\forall i(Z_{i+1}=\{x \in G : \forall y\ xyx^{-1}y^{-1} \in Z_i\})$ then $\exists n(Z_n=G)$

Changed: 42c38,39
$op_2$ is ...: $...$
Remark: Note that $Z_1=Z(G)$, the center of $G$. The smallest $n$ for which $Z_n=G$ is the nilpotence class of $G$. E.g. Abelian
groups are of nilpotence class 1.
