So I have created a possible list for the groups A-C. The new participants have not yet sorted in a group.
In the IC-league #2 - there were the groups A-C each group with 7 participants. In the new AM-league #3 are from the other league 6 participants from the IC-league groups A-C. I put 4 participant in the other groups each group 2 participants.
example: 6 from IC-league group A are now in AM-league group: A 2 - B 2 - C 2.
