Petotetremar

Petotetremar is equal to \(f_{\psi(M\uparrow\uparrow 10^{15})}(10)\) using the fast-growing hierarchy with respect to this OCF \(\psi\) and this system of fundamental sequences. The term was coined by Denis Maksudov
== Etymology ==
The 3 parts of the name, "peto", "tetr" and "emar", mean \(10^{15}\), tetration, and "\(M\)". So the full name indicates the ordinal index of the number.
