Octiphi

Octiphi is equal to \(f_{\varphi(8,0)}(10)\) using the fast-growing hierarchy and Veblen's function's fundamental sequences.My system of number names (FGS) - Traveling To The Infinity The term was coined by wiki user Denis Maksudov.
== Etymology ==
The 2 parts of the name, "octi" and "phi", mean 8 and \(\varphi\) function respectively, which form \(\varphi(8,0)\) when concatenated backwards. So the full name indicates the ordinal index of the FGH.
