Dihexar

Dihexar is equal to \(Q_{1,1}(6)\) in the Q-supersystem.It is approximately \(6\uparrow^{6\uparrow^{6\uparrow^{6\uparrow^{6\uparrow^{6\uparrow^{4} 6} 6} 6} 6} 6} 6\) in up-arrow notation.The number can be computed like this:

Set \(t_{1}=6\uparrow\uparrow\uparrow\uparrow 6\),aka Hexar.

Set \(t_{2}=6\uparrow^{t_{1}-2} 6\).

Set \(t_{n}=6\uparrow^{t_{n-1}-2} 6\).

Dihexar is equal to \(t_6\).

It's name comes from the number "Hexar" and "di",meaning two.The term was coined by Boboris02.
