Maple symgen result This shows Maple’s found \(\xi ,\eta \) and the corresponding canonical coordinates \(R,S\).\begin{align*} \\ \left [R &= y, S \left (R \right ) &= -\frac {1}{x y}\right ] \\ \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 &=\frac {-x \,y^{4}-x \,y^{2}}{-y^{2}+x -1} \\ \frac {dS}{dR} &= 0 \\ \end{align*}
