Trihexar is equal to $$Q_{1,2}(6)$$ in the Q-supersystem.[1] 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 $$t_{t_{t_{t_{t_{t_6}}}}}$$.

Etymology

The name of the number comes from the greek word "tri" meaning three and the number "Hexar".
