- "Googolduduex" redirects here. It is not to be confused with googoldudex.
Googolstackstack is equal to \(10\uparrow\uparrow \text{googolstack}\) or \(10 \uparrow\uparrow 10 \uparrow\uparrow (10^{100})\).[1] It is also called a googolgoogolduplex.[2] It is equal to a power tower of googol-stack tens.
Aarex Tiaokhiao and Username5243 call this number googolduduex.[3][4]
Etymology
The name "googolstackstack" can be separated into 3 parts, "googol" and 2 "-stack"s, where "n-stack" means \(10\uparrow\uparrow n\), so 2 "-stack"s means the operation applying 2 times.
