View full site to see MathJax equation

A tresquinquagintacentillion is equal to \(10^{462}\) in the short scale and \(10^{918}\) in the long scale by the Conway and Guy's naming system^[1]^[2]^[3]^[4] as it is the 153rd -illion number.

In the long scale, \(10^{462}\) is called septenseptuagintillion.
