Gogolplex

The gogolplex (also called googol-sexdecigong or a fiftyplexplex) is equal to 101050 = E50#2 = EE50 using Hyper-E notation. The name was coined by Sbiis Saibian. It is equal to 1 followed by gogol (100 quindecillion) zeros. It is 1050+1 digits long. It is larger than a quindecillionplex (101048).
Writing down the full decimal expansion would take 100 tredecillion (1044) books of 400 pages each, with 2,500 digits on each page (except for the first, which would have 2,501).
