Quintitetrommthet

Quintitetrommthet is equal to \(f_{\theta(\Omega \uparrow\uparrow 5)}(10)\)My system of number names (FGS) - Traveling To The Infinity using the fast-growing hierarchy and Feferman's \(\theta\)-function with this system of fundamental sequences. The term was coined by wiki user Denis Maksudov.
It is also equal to \(f_{\psi(\Omega\uparrow\uparrow 6)}(10)\) using Buchholz's function.
== Etymology ==
The 4 parts of the name, "quinti", "tetr", "omm" and "thet", mean 5, tetration, \(\Omega\) and \(\theta\) function respectively, which form \(\theta(\Omega\uparrow\uparrow5)\) when concatenated backwards. So the full name indicates the ordinal index of the FGH.
