Jonah’s Number is a number invented by Jonah Nichols, or XYZeed, to finally make his first own large number. It can also be called gargoogolplex times 1.91919.... but is commonly referred to as Jonah’s Number. The 19 pattern repeats 1 googol times, making it so that there is 2 googol digits in the number. It is shown as this in the scientific notation - \(1.919...\times 10^{10^{200}}\). This is also, currently, Jonah’s smallest number.
