Tresvigintitrecentillion

A tresvigintitrecentillion is equal to \(10^{972}\) in the short scale and \(10^{1938}\) in the long scale by the and 's naming systemConway and Guy. (1995) "The book of Numbers" Copernicus as it is the 323rd -illion number.
In the long scale, \(10^{972}\) is called duosexagintacentillion.
