Trihexar

Trihexar is equal to \(Q_{1,2}(6)\) in the Q-supersystem.It is comperable to \(f_{\omega+2}(6)\) in the fast-growing hierarchy.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 \(t_{t_{t_{t_{t_{t_6 }}}}} \).The name of the number comes from the greek word "tri" meaning three and the number "Hexar".The term was coined by Boboris02.
