Graham's number is an immense number that arose as an upper bound on the answer of a problem in the mathematical field of Ramsey theory. It is much larger than many other large numbers such as Skewes's number and Moser's number , both of which are in turn much larger than a googolplex .

googolplex = = Skewes's numbers: the first is approximately , the second ; Graham's number, larger than what can be represented even using power towers . However, it can be represented using layers of Knuth's up-arrow notation.
At the same time that he suggested "googol" he gave a name for a still larger number: "googolplex". A googolplex is much larger than a googol, but is still finite, as the inventor of the name was quick to point out. It was first suggested that a googolplex should be 1, followed by writing zeros until you got tired.
Graham's number, one of the largest numbers ever used in serious mathematical proof, is an upper bound for a problem related to Ramsey theory. Another large example is the Boolean Pythagorean triples problem .
(See googolplex for a comparable number) Now let's examine Graham's number, or since we can't look at the number itself, let's look at the tower of powers that appears in that article. That tower has 3^(3^...^3) layers, where the number of 3's in the ellipses is equal to 3^(3^3), which equals about 7.6 x 10^12.
Mathematics:, a number in the googol family called a googolplexplex, googolplexian, or googolduplex. 1 followed by a googolplex zeros, or 10 googolplex Cosmology: The uppermost estimate to the size of the entire universe is approximately 10 10 10 122 {\displaystyle 10^{10^{10^{122}}}} times that of the observable universe .
Graham's number has 64 of the up arrows, so it's much more than what a brain can comprehend without just thinking of infinity. 98.223.56.77 02:14, 22 September 2008 (UTC) Graham's number has many, many, many more than 64 up arrows. g 1 has 4 up arrows. g 2 has g 1 up arrows.
