Maple symgen result This shows Maple’s found \(\xi ,\eta \) and the corresponding canonical coordinates \(R,S\)\begin{align*} \\ \\ \end{align*}

My program’s symgen result This shows my program’s found \(\xi ,\eta \) and the corresponding ODE in canonical coordinates \(R,S\).\begin{align*} \xi &= y \\ \eta &=x \\ \frac {dS}{dR} &= \frac {1}{{\mathrm e}^{2 R^{2}}+R} \\ \end{align*}
