Noninet

Noninet (also called quadriphi) is equal to \(f_{\varphi(4,0)}(10) = f_{\varphi(4,0)[10]}(10)\) 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 3 parts of the name "noninet", "noni", "in" and "et", mean 9, the "in-" operation and \(\eta\)-ordinals respectively, which form \(\varphi(4,0)[10]\) (i.e. 9 more insertions of \(\eta\)) when concatenated backwards. So the full name indicates the ordinal index of the FGH.
The 2 parts of the name "quadriphi", "quadri" and "phi", mean 4 and \(\varphi\) function respectively, which form \(\varphi(4,0)\) when concatenated backwards. So the full name indicates the ordinal index of the FGH.
