Septemoctogintillion

A septemoctogintillion is equal to \(10^{264}\) in the short scale and \(10^{522}\) in the long scale by the and 's naming systemConway and Guy. (1995) "The book of Numbers" Copernicus as it is the 87th -illion number. It may also be called as septenoctogintillion in the modified Conway's system.
In the long scale, \(10^{264}\) is called quattuorquadragintillion.
