Googolstackstackstack is equal to $$10\uparrow\uparrow \text{googolstackstack}$$ or $$10\uparrow\uparrow 10\uparrow\uparrow 10\uparrow\uparrow 10^{100}$$.[1]

## Etymology Edit

The name of this number can be separated into 4 parts, "googol" and 3 "-stack"s, where "n-stack" means $$10\uparrow\uparrow n$$, so 3 "-stack"s means the operation applying 3 times.
