Googolsextiplex

The googolsextiplex, googolsexplex, or googolhexaplex is equal to E100#7 = EEEEEEE100 in Hyper-E notation.
It is also equal to 10101010101010100, or one followed by a googolquinplex (googolplexplexplexplexplex) zeros. It is 101010101010100+1 digits long.
Writing down the full decimal expansion would take 101010101010100-6 books of 400 pages each, with 2,500 digits on each page (except for the first, which would have 2,501).
