Maple symgen result This shows Maple’s found \(\xi ,\eta \) and the corresponding canonical coordinates \(R,S\).\begin{align*} \\ \left [R &= \frac {x^{2}+2 x a +a^{2}+4 y}{4 x^{4}}, S \left (R \right ) &= \frac {\ln \left (x \right )}{2}\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 &=-2 x^{2} \sqrt {a^{2}+2 x a +x^{2}+4 y}+2 a^{2}+4 x a +2 x^{2}+8 y \\ \frac {dS}{dR} &= 0 \\ \end{align*}
