Construct an AON network according to the activity description below. Label activities by their letters and node numbers. Remove redundant relationships and arrange activities in proper sequence steps. Show all calculations.

Activity $H$ is followed by activities V$,$ X$,L$ and $Z.$

Activity $C$ precedes activity $P$ and follows the completion of activities Q$,$ J$,$ and E$.$

The predecessors to activity $N$ are activities $E,K,$ and $F.$

Activity $O$ follows activities $D$ and $N,$ and precedes activity $P.$

Activity J is preceded by activities T$,$ D$,$ and L$.$

Activity I follows activity $U$ and precedes activity $Q.$

Activity $U$ can start when activities $V$ and $x$ are completed.

Activity $D$ follows activity $U.$

Activity E depends on activity L and $H$ and precedes activities T$,$ N$,$ and J$.$

Activity $M$ is preceded by activities $x,L,$ and $Z$ and is followed by activities $K$ and $F$
