Gigophi is equal to \(f_{\varphi(10^9,0)}(10)\) 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, "gigo" and "phi", mean \(10^9\) and \(\varphi\) function respectively, which form \(\varphi(10^9,0)\) when concatenated backwards. So the full name indicates the ordinal index of the FGH.
