line in my problem. That's gonna give me a pretty good clue that I want to use a presentation. And so what I want to do with this permutation is that I want to put these five people in line, so I want to put all five of them in line. So this is a permutation where I have five objects and I want to choose, um, all further there. And so what that's gonna do is make this be that I have five choices for the first person in line four for the second, all the way down to the end. And so, in this case, I have 100 and 20 different choices for how I could put those people in the Lord.
