Help Please With 88-Game Schedule

[jpeters1734]

I'm expanding my 12 team league to 14 teams. At 12 teams, we had no divisions or sub leagues and we played 2 4-game series against all other teams for 88 games total.

At 14 teams, I want to introduce divisions. My options are 7/7 or 6/8. I still want divisions to play each other 2 times in 4-game series. I realize this makes it difficult since you'd have to overlap divisional games with interdivision games.

Here is my request for anyone willing to take this on:

88 games, 4-game series, teams play every team in their division 8 times. Interdivision games can be balance however works. Teams all share common off days.

Divisions can be either 7/7 or 6/8, whatever works best.

Huge thanks to whoever can figure this out!

Note, don't worry about other schedule feature such as times, all-star, etc. I can edit the file myself to set that, I'm just having issues with the structure.

Sounds like you could maybe build the schedule file with structure hints. So I will give just that at least for now considering my evening is almost over.

The 88 games all in 4-game series means 22 series per team. The 7-team divisions has a straightforward solution with two series against each division opponent. The divisions can mirror each other for the intradivision games. The trick is to have the "extra" team in each division that is left out of the division matchups at any given time playing the corresponding team from the other division. Each division matchup is covered through 7 series - 6 against division opponents plus 1 time being the "extra" team. Double that to get the 2 series per opponent, and that covers 14 of the 22 series.

The remaining 8 series would be all interdivision. There are six opponents left to cover after using one in the intradivision, so rotate among them with alternating home and away. That leaves only two more series to cover. Pick out two of the opponents and play them with the opposite home/away flipped from what it was in already-set matchups. So there end up being three of the interdivision opponents in two series and the other four getting only one.

Below is a possible layout as I would start my prep. Each line is seven series that would be occurring at the same time.

1  @ 7		2  @ 6		3  @ 5		4  @ 11		14 @ 8		13 @ 9		12 @ 10
2  @ 1		3  @ 7		4  @ 6		5  @ 12		8  @ 9		14 @ 10		13 @ 11
3  @ 2		4  @ 1		5  @ 7		6  @ 13		9  @ 10		8  @ 11		14 @ 12
4  @ 3		5  @ 2		6  @ 1		7  @ 14		10 @ 11		9  @ 12		8  @ 13
5  @ 4		6  @ 3		7  @ 2		1  @ 8		11 @ 12		10 @ 13		9  @ 14
6  @ 5		7  @ 4		1  @ 3		2  @ 9		12 @ 13		11 @ 14		10 @ 8
7  @ 6		1  @ 5		2  @ 4		3  @ 10		13 @ 14		12 @ 8		11 @ 9
7  @ 1		6  @ 2		5  @ 3		11 @ 4		8  @ 14		9  @ 13		10 @ 12
1  @ 2		7  @ 3		6  @ 4		12 @ 5		9  @ 8		10 @ 14		11 @ 13
2  @ 3		1  @ 4		7  @ 5		13 @ 6		10 @ 9		11 @ 8		12 @ 14
3  @ 4		2  @ 5		1  @ 6		14 @ 7		11 @ 10		12 @ 9		13 @ 8
4  @ 5		3  @ 6		2  @ 7		8  @ 1		12 @ 11		13 @ 10		14 @ 9
5  @ 6		4  @ 7		3  @ 1		9  @ 2		13 @ 12		14 @ 11		8  @ 10
6  @ 7		5  @ 1		4  @ 2		10 @ 3		14 @ 13		8  @ 12		9  @ 11
1  @ 9		2  @ 10		3  @ 11		4  @ 12		5  @ 13		6  @ 14		7  @ 8
10 @ 1		11 @ 2		12 @ 3		13 @ 4		14 @ 5		8  @ 6		9  @ 7
1  @ 11		2  @ 12		3  @ 13		4  @ 14		5  @ 8		6  @ 9		7  @ 10
12 @ 1		13 @ 2		14 @ 3		8  @ 4		9  @ 5		10 @ 6		11 @ 7
1  @ 13		2  @ 14		3  @ 8		4  @ 9		5  @ 10		6  @ 11		7  @ 12
14 @ 1		8  @ 2		9  @ 3		10 @ 4		11 @ 5		12 @ 6		13 @ 7
1  @ 10		2  @ 11		3  @ 12		4  @ 13		5  @ 14		6  @ 8		7  @ 9
13 @ 1		14 @ 2		8  @ 3		9  @ 4		10 @ 5		11 @ 6		12 @ 7

Obviously you would want to reorder the lines. As here all the intredivision games are in the first 14 rows, and the last 8 rows have only interdivision.

Of course! The 7/7 makes a lot of sense now. I should be able to build the schedule using this, thanks! Though I may have to come back for help. I understand the schedule files and can edit them, but I haven't built one from scratch. Thanks for the help!
