I need a schedule for a 36 person golf league that is divided into 3 flights (A, B, and C) and plays for twenty two weeks, (everyone plays each other twice). Flight A is numbered 1 thru 12, flight B is numbered 13 thru 24, and flight C is numbered 24 thru 36. Flight A only plays A, B only plays B and C only plays C. Any help is appreciated.
