Quintaddep

Quintaddep is equal to \(f_{\varepsilon_0+5}(10)\) using the fast-growing hierarchy.My system of number names (FGS) - Traveling To The Infinity The term was coined by wiki user Denis Maksudov.
== Etymology ==
The 3 parts of the name, "quinti", "add" and "ep", mean 5, addition and \(\varepsilon_0\) respectively, which form \(\varepsilon_0+5\) when concatenated backwards. So the full name indicates the ordinal index of the FGH.
