May one person from each of three groups of three separate and form a new zimun group, leaving only two in each original group?
Synopsis
The Rema rules that when each group has only three, one may not depart to form a new group since this would prevent the remaining two from making zimun. With four per group, one may depart. The Mechaber discusses the b'dieved scenario where the original group then zimmered without the departed person.
