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 &= 0 \\ \eta &=x^{2}+2 x y +y^{2}+1 \\ \frac {dS}{dR} &= \frac {\ln \left (2\right )+\ln \left (R \right )}{\ln \left (R \right )} \\ \end{align*}
