Docentation refers to the 200th hyperoperation.[1] It is equal to the binary function \(\uparrow^{198}\), using up-arrow notation. The term was coined by Aarex Tiaokhiao.

"a docentated to b" is also \(\{a,b,198\}\) in BEAF or \(\textrm E[a]\underbrace{1\#1\#1...1\#1\#1}_{197}\#b\) in Hyper-E notation and \(a \rightarrow b \rightarrow 198\) in chained arrow notation.

Docentational growth rate is equivalent to \(f_{199}(n)\) in the fast-growing hierarchy.
