Tarintar

Tarintar is equal to \(f_{\underbrace{C(C(\cdots(C(C(\Omega_{((\text{dekotar})-1)\text{-intar }} 2,0),0),\cdots ),0)}_{\left(\text{dekotar}-1\right)\text{-intar C's}}}(\left(\text{dekotar}-1\right)\text{-intar})\) using the fast-growing hierarchy with fundamental sequences for Taranovsky notation. The term was coined by wiki user Denis Maksudov.

Etymology
The 2 parts of the name, "tar", "in" and "tar", mean dekotar and Tar function (from Taranovsky's notation) respectively, which form \(Tar\)(\(\text{dekotar}\)\(-1\)) when concatenated backwards. So the full name indicates how the number is constructed.
