Seseptuagintacentillion

View full site to see MathJax equation

A seseptuagintacentillion is equal to \(10^{531}\) in the short scale and \(10^{1056}\) in the long scale by the Conway and Guy's naming system^[1]^[2]^[3]^[4] as it is the 176th -illion number.

In the long scale, \(10^{531}\) is called octooctogintilliard.
