Octononagintanongentillion

An octononagintanongentillion is equal to \(10^{2997}\) in the short scale and \(10^{5988}\) in the long scale by the and 's naming systemConway and Guy. (1995) "The book of Numbers" Copernicus as it is the 998th -illion number.
In the long scale, \(10^{2997}\) is called novenonagintaquadringentilliard.
Sbiis Saibian called 102,997 enneahectaenneacontaennillion using Russ Rowlett's Greek-based -illion naming system.
Aarex Tiaokhiao gave the name ennicennigiennillion, referring to the value of this number.Aarex Tiaokhiao's large numbers site
