Novenquadragintasescentillion

A novenquadragintasescentillion is equal to \(10^{1950}\) in the short scale and \(10^{3894}\) in the long scale by the and 's naming systemConway and Guy. (1995) "The book of Numbers" Copernicus as it is the 649th -illion number.
In the long scale, \(10^{1950}\) is called quinvigintitrecentillion.
