Nonexep

Nonexep is equal to \(f_{\varepsilon_0^9}(10)\) using the fast-growing hierarchy.My system of number names (FGS) - Traveling To The Infinity The term was coined by wiki user Denis Maksudov.
It is equal to \(f_{\omega^{\varepsilon_09}}(10)=f_{\varphi_0(\varphi_1(0)\cdot 9)}(10)\) using the Veblen function \(\varphi_\alpha(\beta)\).
== Etymology ==
The 3 parts of the name, "noni", "ex" and "ep", mean 9, exponentiation and \(\varepsilon_0\) respectively, which form \(\varepsilon_0^9\) when concatenated backwards. So the full name indicates the ordinal index of the FGH.
