A novenonagintaseptingentillion is equal to \(10^{2400}\) in the short scale and \(10^{4794}\) in the long scale by the Conway and Guy's naming system[1][2][3][4][5] as it is the 799th -illion number.
In the long scale, \(10^{2400}\) is called quadringentillion.[6]
NumLynx named short-scale value of this number as octingentisand, which is equal to 1000800 = 102400.[7]
RedBandServerYT calls this number yoctesimal-googol.[8]
