Trihexar

Trihexar is equal to \(Q_{1,2}(6)\) in the Q-supersystem.Q-numbers - Beyond and beyond The term was coined by Boboris02.
The number can be computed like this:
* \(t_{1}=6\uparrow\uparrow\uparrow\uparrow 6\), aka Hexar.
* \(t_{n}=6\uparrow^{t_{n-1}-2} 6\).
* Trihexar is equal to \(t_{t_{t_{t_{t_{t_6}}}}}\).
