User blog comment:Undeadlift/Graham's Number using the Supernova Array/@comment-4224897-20150629152038

you're wrong about graham's number being really hard to express compactly. you can express it very compactly like so:

f^64(4) where f(n) = 3^(n)3

also, graham's number is actually pretty weaksauce in the world of googology.
