So now let's put B in seat number one, and I could put A in the middle and C on the right. Or I could put B in seat number one and then swap A and C. So C and then A. And then if I put C in seat number one, well, I could put A in the middle and B on the right. Or with C in seat number one, I could put B in the middle and A on the right. And these are actually all of the permutations. And you can see that there are one, two, three, four, five, six. Now this wasn't too bad, and in general, if you're thinking about permutations of six things or three things in three spaces, you can do it by hand.
