Petaddom

The petaddom is equal to \(f_{\omega+10^{15}}(10)\) 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", "add" and "om", mean \(10^{15}\), addition and \(\omega\) respectively, which form \(\omega+10^{15}\) when concatenated backwards. So the full name indicates the ordinal index of the FGH.
== Approximations ==
Notation 	Approximation
Hyper-E notation 	\(\textrm E3.489 \#10 \#\#8 \#10 \#\#10^{15}\)
Chained arrow notation	\(10 \rightarrow 10 \rightarrow 11\rightarrow (10^{15}+1)\)
BEAF 	\(\lbrace10,11,\{10,15\},2\rbrace\)
