There are several different answers depending on how a subcommittee is formed. For example, is it just four members of the board with equal status so that a committee consisting of Bill, Bob, Brian, and Basil is the same as one formed of Bob, Basil, Bill, and Brian? Or does the subcommittee have a chairman so that a committee consisting of Chairman John plus Joe, Jill, and Jeri is different from one consisting of Chairman Jill plus Joe, John, and Jeri. Perhaps there is a Chairman and a Chairman Pro Tem, so that Chairman Steve, Chairman Pro Tem Scott, Sally, and Sue...get the idea?
