30 team, 162 game schedules
2 leagues, 3 divisions per league, 5 teams per division
60 games in the division (15 per opponent)
60 games outside division (6 per opponent)
42 interleague games (3 vs twelve teams, 2 vs three teams)
See the comments at the top of the files for more details. These are rather unusual schedules in a few ways. They are simply the same as
this 165 game schedule, except one game is trimmed from three of the interleague series. Unfortunately the home/away split totals are not even for all teams. In format "a" the unevenness between the number of home & away interleague games is a little smaller but more randomly distributed among the teams. In format "b" the unevenness is larger is some cases, not there at all in others, but consistent for all teams within each division. Again, see the notes at the top of the file for more specifics.
