The **ecetonplex** is equal to E303#2 = EE303 = 10^{10303}, using Hyper-E notation.^{[1]}^{[2]} The name was coined by Sbiis Saibian. It is equivalent to 1 followed by a centillion zeroes. It is much larger than a googolplex. In fact an ecetonplex is greater than a googolplex raised to the power of a googol, which is (10^{10100})^{10100} = 10^{10200}.

When Sbiis Saibian was young, he called this number **centillionillion**.^{[3]} It is the only name for a large number he came up with during his childhood. Note that "centillionillion" is not a technically accurate name for this number; logically, "centillionillion" should mean the centillionth -illion, or 10^{3*10303+3}. Sbiis Saibian himself notes this on his website.

In the Epstein system,which is based on the long scale,the centillionth illion (the centillionth power of a million,or 1,000,000^{1,000,000100}) is a *centillio-illion*.The 10^{303} power of a million is a *quinquagintillia-illion*.
