I just literally draw it out because especially, you know, I don't like formulas. I like to actually conceptualize and visualize what I'm doing. But you might say, hey, you know, when we just did five different people in five different chairs and we cared which seat they sit in, we had this five factorial. Well, you know, factorial is kind of a neat little operation. How can I relate factorial to what we did just now? Well, it looks like we kind of did factorial, but then we stopped. We stopped at, we didn't go times two times one.
