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}, \underline {\hspace {1.25 ex}}\eta &= y^{2}\right ] \\ \left [R &= -\frac {-1+2 y \ln \left (x \right )}{y}, S \left (R \right ) &= -2 \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 {4 \ln \left (x \right ) y^{3}-3 y^{3}-2 y^{2}}{-2+4 y \ln \left (x \right )-2 y} \\ \frac {dS}{dR} &= 0 \\ \end{align*}
