Zero classes, or one class?

| This is not enirely correct:
| With 6 players,
| In McMahon, you get  N vs N+1, N+2 vs N+3 and N+4 vs N+5
| In Swiss you get  N vs N+3, N+1 vs N+4, N+2 vs N+5

Are you referring to the pairing of opponents for the first round?
In a Swiss system, the players are initially ordered from highest rating
to lowest followed by unrated players, and then for the first round
player 1 plays player (N/2)+1 (halfway down the list), player 2 plays
(N/2)+2, ... , player N/2 plays player N.
