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