Number of teams = 14 teams
Number of divisions = 2
Number of teams in each division = 7

Then;
Total number of pairings = 7C2 = 21
These games happens twice and the same happens on the other division.
Within the same division,
Number of games = 4*21 = 84 games
And number of games  between the two divisions = 7*7 = 49

Total number of games for the conference = 84+49 = 133 games.
