Based Graham's number (English: Graham's number) is a gigantic number that is an upper bound for solving a certain problem in Ramsey theory. It is a very large power of three, written using Knuth's up-arrow notation. It is named after Ronald Graham. It became known to the general public after Martin Gardner described it in his "Mathematical Games" column in Scientific American in November 1977, where it was stated: "In an unpublished proof, Graham has recently established a bound so large that it holds the record as the greatest number ever used in a serious mathematical proof." In 1980, Guinness World Records repeated Gardner's claim, further fueling public interest in this number. Graham's number is unimaginably larger than other well-known large numbers such as googol, googolplex, and even greater than Skewes' number and Moser's number. The entire observable universe is too small to contain a normal decimal representation of Graham's number (assuming that writing each digit occupies at least Planck's volume). Even exponential towers of the form aᵇᶜ... are useless for this purpose (in the same sense), although this number can be written using recursive formulas such as Knuth's up-arrow notation or equivalent ones, which is what Graham did.

In modern mathematical proofs, numbers that are still much larger than Graham's number sometimes appear, for example in work with Friedmann's finite form in the Kruskal-Katona theorem — the so-called TREE(3). ...024259506950647383956574791365 193517 98334535362521 43003540126026771622672160419810 65226 3169355188780 3881448314065252616878509555264 605107 1172000997092 9124954437888749606288291172506 300130 3622934916080 2545946149457887142783235082924 21020 01825896753560 4308699380168924988926809951016 90559 19951195027887 1783083701834023647454888222216 157322 8010132974509 273445945043433009010969280253 52751 833289884461508 9404248265018193851562535796399 618993 9679054966380 0322234872396701848518643905910 45756 27262464195387 #fyp #turkiye #ottomanempire #memes #NowVSThen - @gabrielkraljevictt
