Duotrigintatrecentillion

A duotrigintatrecentillion is equal to \(10^{999}\) in the short scale and \(10^{1992}\) in the long scale by the and 's naming systemConway and Guy. (1995) "The book of Numbers" Copernicus as it is the 332nd -illion number.
In the long scale, \(10^{999}\) is called sesexagintacentilliard.
Sbiis Saibian named \(10^{999}\) as trecenti-triginti-deutillion in the short scale and centi-sexaginti-sextilliard in the long scale.Sbiis Saibian. Ultimate Large Number List Retrieved 2023-02-28.
