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