Octultep

Octultep is equal to \(f_{\varepsilon_0\times 8}(10)\) 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, "octi", "ult" and "ep", mean 8, multiplication and \(\varepsilon_0\) respectively, which form \(\varepsilon_08\) when concatenated backwards. So the full name indicates the ordinal index of the FGH.
