Hello there! While I'm not apart of the group you're currently in, I can answer a few of your questions. A Group is a private community where members can congregate and discuss whatever they want. A Clan is not a Group (Technically), Clans are limited to 100 members per platform (PlayStation/Xbox) per Group. A Group has an unlimited number of members that can share discussion together. Clan rosters are monitored by the Group Founder and Administration and members have the option to change them. You can only be a member of one Clan at a time while you can be a member of fifty Groups. This link has all the information you need on Groups or Clans. I'll leave it here for your convenience.
