How Many Segments Can You Do With Six?

You can do all sorts of crazy shapes that turn on or off. As long as they come all on and all off at once. The question now is, how few could you go? And there is an absolute limit. You cannot do it with three because if you've only got three things you can turn on oroff. There were only eight different combinations of turning three things on or off in the show. So I thought I would see if I could get four, which is a big old reduction on six. If you could crack a better three, I'd really appreciate that.
