>> BRADY HARAN: I think most Numberphiles are fascinated by the idea of Graham's number,which is supposedly unimaginably big -but what actually is it? What does it count?Well, I think the best person to explain thatis none other than the world famous mathematician himself, Ron Graham.>> RON GRAHAM: Suppose you took four vertices of a square -and, this is two dimensons, so it has how many vertices?Two squared (four vertices).Now, what I'm going to do is take these four vertices, and put -two more edges connecting all possible pairs of these vertices.Now how many possible edges would you be able to draw?Well, there's something called a binomial coefficient,and there are four vertices, and you choose two of them,and ...
