@mayograpist: Graham's number is a giant number that is the upper limit for solving a certain problem in Ramsey's theory. It is a very large power of three, which is written using Knuth notation. 1 Named after Ronald Graham. It became known to the general public after Martin Gardner described it in his column "Mathematical Games" in Scientific American magazine in November 1977. In 1980, the Guinness Book of Records repeated Gardner's claims, further fueling public interest in this number. 1 The Graham number is an unimaginable number of times larger than other well-known large numbers such as the googol, googolplex, and even larger than the Skews number and the Moser number.
