Duoquadragintasescentillion

A duoquadragintasescentillion is equal to \(10^{1929}\) in the short scale and \(10^{3852}\) in the long scale by the and 's naming systemConway and Guy. (1995) "The book of Numbers" Copernicus as it is the 642nd -illion number.
In the long scale, \(10^{1929}\) is called unvigintitrecentilliard.
