    Graham's number

     

    Graham's number, named after Ronald Graham, is often described as the largest number that has ever been seriously used in a mathematical proof. It is too large to express in scientific notation so it needs special notation (G) to write down. Graham's number is much larger than other well known large numbers such as a googol and a googolplex, and even larger than Moser's number, another well-known large number.

     

     

    Graham's problem

    Graham's number is connected to the following problem in the branch of mathematics known as Ramsey theory:

    Consider an n-dimensional hypercube, and connect each pair of vertices to obtain a complete graph on 2n vertices. Then colour each of the edges of this graph using only the colours red and black. What is the smallest value of n for which every possible such colouring must necessarily contain a single-coloured complete sub-graph with 4 vertices that lies in a plane?

     

    Although the solution to this problem is not yet known, Graham's number is the smallest known upper bound for it. This bound was found by Graham and B. L. Rothschild (see (GR), corollary 12). They also provided the lower bound 6, adding the qualifying understatement: "Clearly, there is some room for improvement here."

     

    In Penrose Tiles to Trapdoor Ciphers, Martin Gardner wrote, "Ramsey-theory experts believe the actual Ramsey number for this problem is probably 6, making Graham's number perhaps the worst smallest-upper-bound ever discovered." More recently Geoff Exoo of Indiana State University has shown (in 2003) that it must be at least 11 and provided evidence that it is larger.

    ummm I would start a new thread, but it seems pointless since I have the same problem, do you think you could do the same for me?
