@zeon4k: my friend dancing to music, right? not my ib 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 named after mathematician Ronald Graham. The number is so large that the observable universe is far too small to contain an ordinary digital representation of it, even assuming that each digit occupies one Planck volume. Even the number of digits in Graham's number is itself a number so large that its digits cannot be written down in the observable universe. It was recognized by the Guinness Book of World Records in 1977 as the largest specific number ever used in a serious mathematical proof. It has since been surpassed by even larger numbers, such as TREE(3). #grahamnumber #fyp #tcc #rampage #tccedit
