Ennalogialogue

The ennalogialogue is equal to E1#9#2 using Hyper-E notation. The term was coined by Sbiis Saibian. In arrow notation, this number is equal to \(10↑↑10↑↑9\).
== Etymology ==
The 2 parts of the name, "ennalogia" and "logue" means Ennalogue and \(10↑↑\text{n}\), which formed \(10↑↑10↑↑9\) when concentrated from left to right. So the full name indicates how the number is constructed.
