Graham's Number

. . . because size matters.

Way Beyond the Limits of the Known Universe

概要

"GRAHAM'S NUMBER," named after mathematician Ron Graham, is so vast that it held the world record for the largest number ever used in a serious mathematical proof. Graham's number is much larger than other large numbers such as a googol and a googolplex. In fact, the observable universe is far too small to contain a written representation of Graham's number.
