@breadxxxd: Repost | Graham's number is the largest number ever used in a mathematical proof. Ronald Graham introduced it in 1977 when addressing a problem in Ramsey theory. Below, summarize its construction, scale, and a curious fact. It is so large that it cannot be written out completely, even using the entire observable universe. ^2,5 READ Details about Graham's number Construction: It is defined by a sequence of operations using Knuth's arrow notation. It starts at 3 and repeatedly applies exponential operations until it reaches the term G64. ^2,3,4 Scale: It is immensely larger than numbers like googol and googolplex. Recording all its digits would require more space than the universe offers. ^{5<|sup> Curiosity: Even with this magnitude, its final digits are known. The last digit is 7. #fyp #fypシ #tcc #davidkatz #zeroday}
