And the number of teams.
Elimination system is a kind of competition system in sports competitions and other competitions. Players play against each other, and they will be eliminated if they lose one game. Eliminate half of the players in each round until the final champion is produced.
Round robin means that each team can compete with other teams once or twice, and finally calculate the ranking according to the score (goal difference). This kind of competition is reasonable, objective and fair, which is beneficial for teams to learn from each other and exchange experiences.

Elimination group arrangement
For example, there are 16 people participating in the competition. In order to make the number of teams in each group even, it can be divided into 4 groups with 4 teams in each group. If time and funds permit, and you want to play more games, you can also divide into two groups, with 8 teams in each group.
Divided into four groups, the "seed team" can be divided into four groups, eight groups, and drawn into the group, or 1, 8, 2, 7, 3, 6, 4, 5 (according to the ranking of the last competition).
In another serpentine arrangement, 1, 4, 5 and 8 "seed teams" are arranged in the first group, 2, 3, 6 and 7 "seed teams" are arranged in the second group, and other teams are drawn into this group.
If the single round robin system is adopted in the final of the second stage, 5-8 players will be decided by taking the first 1 of the four teams (the third and fourth of the two teams) as a group. The rest and so on, determine all the rankings.
In the second stage of the finals, if the second round with the same name is adopted, the runner-up of 1 in the two groups will win the championship, and the second runner-up in the two groups will win 3 to 4 places, and so on, and all the rankings will be determined.
