Googolstackstack

Googolstackstack is equal to \(10\uparrow\uparrow \text{googolstack}\) or \(10 \uparrow\uparrow 10 \uparrow\uparrow (10^{100})\).Cantor's Attic It is also called a googolgoogolduplex.bigΨ section 1.5.2. Googol world It is equal to a power tower of a googolstack tens.

== 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.
