A googolquinplex or googolquintiplex or googolpentaplex or googolplexplexplexplexplex[1] is a number equal to one with a googolquadriplex zeroes after it, or 101010101010100.[2][3] In Hyper-E Notation it can be written E100#6.[4] In down-arrow notation it can also be written \(10 \downarrow\downarrow (10^{10^{10^{10^{100}}}}+1)\). It is 1010101010100+1 digits long.
Writing down the full decimal expansion would take 1010101010100-6 books of 400 pages each, with 2,500 digits on each page (except for the first, which would have 2,501).
Etymology[]
The name of this number is based on Latin prefix "quin-" and the number "googolplex".
Other names[]
Using Aarex Tiaokhiao's -illion generalization of Nirvana's -illions, this number is approximately:[5]
DeepLineMadom calls the number troogolquintiplex and troogolquinplex, and is equal to 10[3]10[3]10[3]10[3]10[3]10[3]100 in DeepLineMadom's Array Notation[6].
