That's Benjamin Graham. (since there's another reply, the parent article points to the wrong Graham).

    3 ↑↑↑↑ 3 = g1, Graham's Number is g64. See the article for details. I'd write it out, but this margin is too narrow.

      I find it stupidly fascinating how notation compressed a quantity so large in so few.

WaitButWhy has a great longform piece explaining how big Graham’s number is. Like, make your stomach drop, big. Bonus, it contains an explanation of Knuth notation. https://waitbutwhy.com/2014/11/1000000-grahams-number.html https://waitbutwhy.com/2014/11/1000000-grahams-number.html

  And then you get Tree(3) which when compared means "[Graham's number] might as well be 1". https://joshkerr.com/tree3-is-a-big-number-i-mean-really-big/ https://joshkerr.com/tree3-is-a-big-number-i-mean-really-big... Maths is wacky.
