when I use summon lesser demons, can I summon one of them inside the circle of protection? Thanks. Yes

What if the creature would be bigger than the circle? Like with summon greater. Would it still work? Thanks for responding. pic.twitter.com/yhqZCxrLCO

Believe it means creature can cross circle; would not contain it
