The ecetonplex is equal to E303#2 = EE303 = 1010303, using Hyper-E notation. 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 (1010100)10100 = 1010200.
When Sbiis Saibian was young, he called this number centillionillion. 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 103*10303+3. Sbiis Saibian himself notes this on his website.
