Hektinamus

Hektinamus is equal to \(f_{\psi(\upsilon[100])}(10)\) using the fast-growing hierarchy with this system of fundamental sequences, \(\upsilon[0]=M(0;0)\) and \(\upsilon[n+1]=M(\upsilon[n];0)\). The term was coined by Denis MaksudovMy system of number names (FGS) - Traveling To The Infinity.
== Etymology ==
The 4 parts of the name, "hekt", "in", "am", and "us", mean \(100\), "in-" operation, \(\alpha\)-Mahlo cardinals, and this ordinal collapsing function, which form \(\psi(\upsilon[100])\) (i.e. 100 more insertions of \(M(\alpha ;0)\)) when concatenated backwards. So the full name indicates the ordinal index of the number.
