Petultom

The petultom is equal to \(f_{\omega10^{15}}(10)\) 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, "peto", "ult" and "om", mean \(10^{15}\), multiplication and \(\omega\) respectively, which form \(\omega10^{15}\) when concatenated backwards. So the full name indicates the ordinal index of the FGH.
