How large does a team get? There's no official limit, but most have between twelve and sixteen - rarely more than twenty-four, because it's very difficult to find that many well-matched twirlers. If you try to put more than twenty-four on a team, you'll probably be limiting the range of difficulty and variety in the routine - and increase the likelihood of penalties.
