The googol-stack is equal to \(10\uparrow\uparrow(10^{100})\) in up-arrow notation.[1] It is also known as a googolgoogolplex.[2] It is equal to a power tower of a googol tens.

Sbiis Saibian calls this number googologue, and it's equal to E1#10100 using Hyper-E notation.[3]

Etymology Edit

The name "googol-stack" comes from the -stack suffix which, when applied to a number x, turns it into \(10 \uparrow\uparrow x\).
