I am interested in the nonabelian finite $p$-group $G$ with the following property:
$G$ has a maximal abelian subgroup $A$ and there exists an $x\in G\setminus A$ such that $x$ normalize $A$ but $x$ does not commute with any noncentral element of $A$.
$p$-groups with maximal class have this property since they have maximal abelian subgroup of order $p^2$. Any reference or comment or maybe partial characterization will be useful for me.
