What is the minium that one must say with a minyan to count as if he prayed with a minyan?
Since "tefillah" when mentioned in the Talmud referrs to the Amidah is it safe to assume that only praying the Amidah with a minyan is what's necessary to count as if you prayed with a minyan? Or, is the shema and/or pesukei dizimra also included?
Practical difference: when you come late to synagogue and need to catch up - does saying shema and pesukei with or without the congregation make a difference?
