Quadhexar is equal to \(Q_{1,3}(6)\) in the Q-supersystem. The term was coined by Boboris02. It can be computed like this: * \(t_{1}=6\uparrow\uparrow\uparrow\uparrow 6\), aka Hexar. * \(t_{n}=6\uparrow^{t_{n-1}-2} 6\) * Quadhexar is equal to \(t_{t_{t_{\ldots_{t_6}}}}\), where there are \(t_{t_{t_{\ldots_{t_6}}}}\) \(t's\), where there are \(t_{t_{t_{\ldots_{t_6}}}}\) \(t's\), where there are \(t_{t_{t_{\ldots_{t_6}}}}\) \(t's\), where there are \(t_{t_{t_{\ldots_{t_6}}}}\) \(t's\), where there are \(t_{t_{t_{t_{t_{t_6}}}}}\) \(t's\).
