Maple symgen result This shows Maple’s found \(\xi ,\eta \) and the corresponding canonical coordinates \(R,S\).\begin{align*} \left [\underline {\hspace {1.25 ex}}\xi &= \frac {x^{2} \left (2 y +1\right )}{2}, \underline {\hspace {1.25 ex}}\eta &= 0\right ] \\ \left [R &= y, S \left (R \right ) &= -\frac {2}{\left (2 y+1\right ) x}\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 {-4 x^{2} y^{2}-4 x^{2} y -x^{2}}{4 x^{2} y^{4}+6 x^{2} y^{3}+2 x^{2} y^{2}+4 x^{2} y +2 x^{2}-4 x} \\ \frac {dS}{dR} &= 0 \\ \end{align*}
