Terultep

Terultep is equal to \(f_{\varepsilon_0\times10^{12}}(10)\) 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, "tero", "ult" and "ep", mean \(10^{12}\), multiplication and \(\varepsilon_0\) respectively, which form \(\varepsilon_010^{12}\) when concatenated backwards. So the full name indicates the ordinal index of the FGH.
