How to arrange the round robin and knockout? What's the trick?

Analysis:

Compilation method of circulation system:

The formula for calculating the number of players in a single loop game is n (n- 1)/2, that is, the number of players (number of players-1)/2 = the total number of players.

Six-person competition round table

The first, second, third, fourth and fifth rounds.

1—6 1—5 1—4 1—3 1—2

2—5 6—4 5—3 4—2 3—6

3—4 2—3 6—2 5—6 4—5

After arranging the round table, everyone draws lots, fills in everyone's name on the round table according to the drawn number, and then prepares the competition schedule and distributes it to each team.

If it is a multi-player competition, the compilation method is similar.

Note: The position of "1" in the upper left corner of the round table remains unchanged, and other numbers are rotated counterclockwise in turn.

The elimination system is a random draw after the table is made.
