Googol-duodecigong

The googol-duodecigong is equal to 101038 = E38#2 = EE38 using Hyper-E notation. The name was coined by Sbiis Saibian. It is 1038+1 digits long. It is bigger than an undecillionplex (101036), and slightly smaller than a duodecillionplex (101039).
Writing down the full decimal expansion would take 1032 books of 400 pages each, with 2,500 digits on each page.
