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