[RoboCup-humanoid] I have a few questions about robocup 2022 humanoid KidSize(physical competition)!

Dear Sir, Hello! I have the following questions, so I send you an email.

1. (About Registration Fees) 1)For humanoid kidssize is it part of Major Leagues registration? 2)If our team is 10 people, is the team registration fee of $790 and the student registration fee of $380 per person, a total of $4590? -Above of the questions are written in the material, but I will ask for confirmation.

2.(About Lows of the Game) - KidSize, physical competition RoboCup Soccer Humanoid League Laws of the Game 2021/2022 describes the ball, but can you give more detailed information about the ball (photo of the ball)?

Thank you for your help in this matter!
