May 12 awarded Yearling May 10 accepted $N_Q(R)=N_Q(Q\cap R)$ where $Q, R \le P$, $Q$ normal and $P$ a $p$-group May 10 comment $N_Q(R)=N_Q(Q\cap R)$ where $Q, R \le P$, $Q$ normal and $P$ a $p$-group I don't see how $R$ would necessarily be normal if $N_Q(R)=Q$. Why can there not exists $x\in P\setminus Q$ such that $xRx^{-1} \neq R$? May 10 asked $N_Q(R)=N_Q(Q\cap R)$ where $Q, R \le P$, $Q$ normal and $P$ a $p$-group
