When it is necessary to determine that two players will participate in the finals, Group A and Group C will be eliminated, and a rematch will be held between Group A, Group B and Group A. After the rematch, the winner and Group A will participate in the finals.

(3) After a certain preliminaries, the results of athletes A and B in Group A are the same as those of athletes A and B in Group B.
