12 person round robin tournament

[dpiasecki1]

I need to make a schedule for a 12 person round robin tournament that features 11 different locations. Each person will have to play each game once and all games will happen simultaneously so I cannot have a location be used twice in any round.

12 person
11 locations


Thanks

I think the following should work as each person (numbered 0 to 11) should appear once in every row and column.

(0 11)	(4 8)		(1 2)	(5 10)	(9 7)				(3 6)
	(1 11)	(5 9)		(2 3)	(6 0)	(10 8)				(4 7)
(5 8)		(2 11)	(6 10)		(3 4)	(7 1)	(0 9)
	(6 9)		(3 11)	(7 0)		(4 5)	(8 2)	(1 10)
		(7 10)		(4 11)	(8 1)		(5 6)	(9 3)	(2 0)
			(8 0)		(5 11)	(9 2)		(6 7)	(10 4)	(3 1)
(4 2)				(9 1)		(6 11)	(10 3)		(7 8)	(0 5)
(1 6)	(5 3)				(10 2)		(7 11)	(0 4)		(8 9)
(9 10)	(2 7)	(6 4)				(0 3)		(8 11)	(1 5)
	(10 0)	(3 8)	(7 5)				(1 4)		(9 11)	(2 6)
(3 7)		(0 1)	(4 9)	(8 6)				(2 5)		(10 11)
