Zettinemar

Zettinemar is equal to \(f_{\underbrace{\psi(M_{M_{..._{M}}})}_{10^{21}+1 \quad M's}}(10)\) using the fast-growing hierarchy. The term was coined by Denis Maksudov
== Etymology ==
The 3 parts of the name, "zetto", "in" and "emar", mean \(10^{21}\), the "in-" operation, "\(M\)", and a certain collapsing function \(\psi\). So the full name indicates the ordinal index of the number.
