Googolduplex in zeroes
Googolduplex[1] is a number equal to \(10^{10^{10^{100}}}\), or 1 followed by a googolplex zeroes. In Hyper-E notation, it is equal to E100#3.
The number has many alternative names such as googolplexplex[2], googolplusplex[3], gargoogolplex[4], googolduplex[5], googolplex2[5], and googolplexian[6].
Ten to the power of googolduplex, \(10^{10^{10^{10^{100}}}}\), is called googoltriplex.
Googolplexian is also equal to "10 to the power of itself googol times".
Etymology 
Edit
After backforming the "-plex" suffix from "googolplex," the term "googolplexplex" follows naturally as double application of the suffix to googol. Googologists shortened this to "duplex," from the Greek prefix for "two," indicating that the "plex" suffix should be applied twice. "Googolplusplex," "gargoogolplex," and "googolplexian" do not appear to be of any logical etymology, other than being various mutations of googolplex.
