Very nice - thanks for posting the link. If anyone is interested here is an example of the 24 players in 11 days of threesomes schedule that is missing from the demonstration (it uses a near solution with foursomes instead):
( 1 2 4) ( 3 7 13) ( 5 11 18) ( 6 22 23) ( 8 16 17) ( 9 12 20) (10 14 24) (15 19 21)
( 2 3 5) ( 4 8 14) ( 6 1 19) ( 7 12 23) ( 9 17 18) (10 13 21) (11 15 24) (16 20 22)
( 3 4 6) ( 5 9 15) ( 7 2 20) ( 8 13 23) (10 18 19) (11 14 22) ( 1 16 24) (17 21 12)
( 4 5 7) ( 6 10 16) ( 8 3 21) ( 9 14 23) (11 19 20) ( 1 15 12) ( 2 17 24) (18 22 13)
( 5 6 8) ( 7 11 17) ( 9 4 22) (10 15 23) ( 1 20 21) ( 2 16 13) ( 3 18 24) (19 12 14)
( 6 7 9) ( 8 1 18) (10 5 12) (11 16 23) ( 2 21 22) ( 3 17 14) ( 4 19 24) (20 13 15)
( 7 8 10) ( 9 2 19) (11 6 13) ( 1 17 23) ( 3 22 12) ( 4 18 15) ( 5 20 24) (21 14 16)
( 8 9 11) (10 3 20) ( 1 7 14) ( 2 18 23) ( 4 12 13) ( 5 19 16) ( 6 21 24) (22 15 17)
( 9 10 1) (11 4 21) ( 2 8 15) ( 3 19 23) ( 5 13 14) ( 6 20 17) ( 7 22 24) (12 16 18)
(10 11 2) ( 1 5 22) ( 3 9 16) ( 4 20 23) ( 6 14 15) ( 7 21 18) ( 8 12 24) (13 17 19)
(11 1 3) ( 2 6 12) ( 4 10 17) ( 5 21 23) ( 7 15 16) ( 8 22 19) ( 9 13 24) (14 18 20)
Each player plays with all but one of the others - the missing pairs being (1 13), (2 14),...,(10 22), (11 12) & (23 24)
