Ecetonplex

Ecetonplex in zeroes

The ecetonplex (also called a centillionplex) is equal to E303#2 = EE303 = 1010303, using Hyper-E notation.[1][2] The name was coined by Sbiis Saibian. It is equal 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 (also known as gargoogol-plexed).

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 103*10303+3. Sbiis Saibian himself notes this on his website.

Written out in decimal form ecetonplex is:

101000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000

Writing down the full decimal expansion would take 10297 books of 400 pages each, with 2,500 digits on each page.
