The company is going to hold a table tennis competition, and every employee is required to participate, about 100 people. How to make rules?

Because of the large number of people, it is suggested to divide into four groups, and then draw lots to ensure that about one-third of the people in the first two rounds have a bye (that is, they can advance directly to the next round without playing). It is suggested to win two out of three games on the eleven-point scale. Then there should be more than 30 people left after the fight, and then eight people in each of the four groups. If there are 10 people left, you can draw lots to decide that 6 people will pass and 4 people will be eliminated. Make sure there are 8 people left in each group, and then after the top 32, the first place in each group will play the eighth, second, seventh, third, fifth, fourth and fourth place in a group (the order has been decided by drawing lots when there are 8 people left). Then you can 16 in 8 8 in 4. Four into two can become three wins in five games, and then four wins in seven games in the final.
