On Daf 8 Amud b in the Yerushalmi note 3f you changed the girsa from rabonon to Rebbi which makes sense but you quote him from the Mishna and he does not appear in the mishna or in the yerushalmi at all only in a braisa quoted in the bavli.
>>(f) Question: (In the Mishnah) Rebbi says that 277 people are required to inhabit the city. What is Rebbe's reasoning?<<
