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 &= 0, \underline {\hspace {1.25 ex}}\eta &= \frac {x^{2}-4 x +4 y}{2 x^{2}-8 x +8 y +8}\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 {-2 x^{2}+8 x -8 y}{x^{2}-4 x +4 y +4} \\ \frac {dS}{dR} &= \frac {R}{4} \\ \end{align*}
