Dihexar is equal to \(Q_{1,1}(6)\) 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.
  • \(t_{2}=6\uparrow^{t_{1}-2} 6\).
  • \(t_{n}=6\uparrow^{t_{n-1}-2} 6\).
  • Dihexar is equal to \(t_6\).

Etymology Edit

The name comes from the number "Hexar" and "di", meaning two.
