Suppose Alex, Bob, Charles, David, Evan, Frankenstein and Gary are seven friends who want to watch a movie. However, at the theater, only one row has seven adjacent empty seats P 1 through P 7 left, with P 1 and P 7 both aisle seats (and none of the others are aisle seats). They find out a few facts about themselves, which are given as follows. Bob wants precisely one (filled) seat between himself and Charles. Gary and Charles want aisle seats, but Gary won’t sit in P 1. With these constraints, how many ways can the seven friends sit in the theater?
