Googolseptigong

The googolseptigong is equal to 101023 = E23#2 = EE23 using Hyper-E notation. The name was coined by Sbiis Saibian. It is equal to 1 followed by 100 sextillion zeros. It is 1023+1 digits long. It is bigger than a sextillionplex (101021), and slightly smaller than a septillionplex (101024).
Writing down the full decimal expansion would take 1017 books of 400 pages each, with 2,500 digits on each page.
