 There are multiple variables of the trips formation, and it may be combined with other types of formations.For example, the call "Shotgun, trips right, slot left" formation would indicate that the tight end and two wide receivers would line up on the right side of the field, while two receivers would line up on the left side of the field (one "wide", the other slightly off the line of scrimmage in the "slot").The quarterback would line up at least five yards behind the center.
