Talk:Dupertri

FGH approximation
I think \(f_{\omega^{\omega}+1}(3)\) is much larger than dupertri. \(f_{\omega^{\omega}+1}(2)\) is closer, f_{\omega^{\omega}}(tritri) is even better.

\begin{eqnarray*} f_{\omega^{\omega}+1}(3) &=& f_{\omega^{\omega}}^3(3) > f_{\omega^{\omega}}^2(tritri) \\ &\approx& f_{\omega^{\omega}}(dupertri) \\ \end{eqnarray*}
