And if we wanted to write it in the notation of permutations, we would say that this is equal to, we're taking 26 things, sorry, not 2p, 20, my brain is malfunctioning, 26, we're figuring out how many permutations are there for putting 26 different things into three different spaces. And this is 26 if we just blindly apply the formula, which I never suggest doing. It'd be 26 factorial over 26 minus three factorial, which would be 26 factorial over 23 factorial, which is going to be exactly this right over here because the 23 times 22 times 21 all the way down to one is going to cancel with the 23 factorial. And so the whole point of this video, there's two points, is one, as soon as someone says, oh, how many different letters could you form or something like that, you just don't blindly do permutations or combinations. You think about, well, what is being asked in the question here? I really just have to take 26 times 26 times 26. The other thing I want to point out, and I know I keep pointing it out and it's probably getting tiring to you, is even when permutations are applicable, in my brain at least, it's always more valuable to just try to reason through the problem as opposed to just saying, oh, there's this formula that I remember from weeks or years ago in my life that had n factorial and k factorial and I have to memorize it, I have to look it up, always much more useful to just reason it through.
