Hi all, I've found something near I want, I guess you can help me out.

Well, I have 49 members of a commitee and I'd like to introduce them in groups of 7. There will be rounds to change spots.
None of the groups can repeate any member.
I need to create the unique groups of names.

Can anyone create a sheet with macro or something like that please? If it's not a problem, I'd like to be able to change the number of members and also the group size. I may introduce them in groups of 3, maybe 4.

Sorry for any grammar mistake, it's not my main language.
