Ecetonthrong

The ecetonthrong is equal to 10303,000,000,000, or E303,000,000,000 using Hyper-E notation. The name was coined by Sbiis Saibian. It is equal to 1 followed by 303 billion zeros. It is 303,000,000,001 digits long.
Writing down the full decimal expansion would take 303,000 books of 400 pages each, with 2,500 digits on each page (except for the first, which would have 2,501).
