There are 329 different grids for the 17 teams, on account of it being so long and thus allowing so many possible solutions. The above grid, shown in abbreviated form, is just one of them.

In each group, the game shown is repeated 16 more times (giving 17 games in each group in total), stepped down one spot each time, to give the same diagonal appearance that you can see in other grids (the 7 or the 16, for example). In the first three groups, you may wish to then further rearrange to avoid back-to-backs.

Another interesting grid is one with marks in squares 1,2,5; 1,2,5; 1,2,5; 1,3,10; 1,3,10; 1,3,9; 1,6,11; 1,6,12; repeated diagonally. This one is interesting because the first column is repeated three times, so you can rearrange it into a single 51 game group, in which each group of three games all contain the same three teams, playing a different colour each time. Thus you can have only three to five teams on site, either playing or waiting to play, at any one time. A similar trick can be pulled with the fourth, fifth and maybe sixth groups, and maybe with the seventh and eighth groups.
