Sesviginticentillion

A sesviginticentillion is equal to \(10^{381}\) in the short scale and \(10^{756}\) in the long scale by the and 's naming systemConway and Guy. (1995) "The book of Numbers" Copernicus as it is the 126th -illion number.
In the long scale, \(10^{381}\) is called tresexagintilliard.
