Googoloctigong

The googoloctigong is equal to 101026 = E26#2 = EE26 using Hyper-E notation. The name was coined by Sbiis Saibian. It is equal to 1 followed by 100 septillion zeros. It is 1026+1 digits long. It is bigger than a septillionplex (101024), and slightly smaller than a octillionplex (101027).
Writing down the full decimal expansion would take 1020 books of 400 pages each, with 2,500 digits on each page.
