So this is head A, and this right over there is head B. So if you had a particular, I mean, these heads are identical. These outcomes aren't different. But the way we talk about it right now, it looks like there's 4 places that we could get this head in, and there's 3 places where we could get this head in. And so if you multiply all of the different ways that you could get all of the different scenarios where this is in 4 different places, and then this is in one of the 3 leftover places, you get 12 different scenarios. But there would only be 12 different scenarios if you viewed this as being different than this. And let me rewrite it with our new.
