What eruv arrangement is required for a nun-shaped alleyway (large central alleyway with many small alleyways branching off, each opening to reshut ha-rabim on the other end)?
Synopsis
In a nun-shaped configuration, each small alleyway requires a tzurat ha-petach where it opens into the large alleyway, and a lechi or korah at its other end (opening to reshut ha-rabim). The large alleyway itself needs tzurat ha-petach on one side and lechi/korah on the other if pass-through, or just lechi/korah if closed on one end.
