The googolnoniplex (also known as googolenneaplex, googolnonaplex, or googolplexplexplexplexplexplexplexplexplex) is equal to E100#10 = EEEEEEEEEE100 in Hyper-E notation.[1]

It is also equal to $$^{11}10^{2}$$ = 10101010101010101010100, or a 1 with a googoloctiplex zeroes. It is 101010101010101010100+1 digits long.

Writing down the full decimal expansion would take 101010101010101010100-6 books of 400 pages each, with 2,500 digits on each page.
