What eruv arrangement is required for a chet-shaped alleyway (bent twice, with two bends and two exits)?
Synopsis
A chet-shaped alleyway (two bends, two exits to reshut ha-rabim) requires a tzurat ha-petach at each of the two bends, and a lechi or korah at each of its two ends. The Rashba holds it only needs lechi/korah at the two ends like a simple closed alleyway.
