Orlenka,

Disbanding is the term you are looking for.

 

Disbanding groups

While there's no explicit mechanism for simply deleting a group while it has members, you can disband a group in which you are an owner by ejecting all the other members and making sure nobody new can join the group.

After 48 hours with a membership of one or zero, a group is disbanded automatically.

Note: Once you disband a group, you cannot recreate it. You can create a new group, but the new group cannot use the exact same name as the dissolved group.
