A googolstackbang is equal to \((10\uparrow\uparrow \text{googol})!\) or \({\text{googolstack}}!\) [1]
Etymology
The name of this number can be separated into 3 parts, "googol", "-stack" and "-bang", where "n-stack" means \(10\uparrow\uparrow n\), and suffix "-bang" means factorial operation. To get the name, the "-stack" first applies on the "googol", then the "-bang" applies on the "googolstack".
