A distribution group is a group of two or more people that appears as its own item in the Address Book. A distribution group has its own email address, but it is not a mailbox. When an email message is sent to a distribution group, it gets distributed to all members of that group.
The person that submits the request for the group creation is defined as the manager (contact person) for the group, and they are also listed as the first owner of the group.
