Maple symgen result This shows Maple’s found \(\xi ,\eta \) and the corresponding canonical coordinates \(R,S\)\begin{align*} \\ \\ \end{align*}

\begin{align*} \left [\underline {\hspace {1.25 ex}}\xi &= 0, \underline {\hspace {1.25 ex}}\eta &= x^{6} {\mathrm e}^{-\frac {x^{2}}{2}}\right ] \\ \left [R &= x, S \left (R \right ) &= \frac {{\mathrm e}^{\frac {x^{2}}{2}} y}{x^{6}}\right ] \\ \end{align*}

\begin{align*} \left [\underline {\hspace {1.25 ex}}\xi &= 0, \underline {\hspace {1.25 ex}}\eta &= x^{2} \left (\operatorname {expIntegral}_{1}\left (-\frac {x^{2}}{2}\right ) x^{4} {\mathrm e}^{-\frac {x^{2}}{2}}+2 x^{2}+4\right )\right ] \\ \left [R &= x, S \left (R \right ) &= \frac {{\mathrm e}^{\frac {x^{2}}{2}} y}{x^{6} \operatorname {expIntegral}_{1}\left (-\frac {x^{2}}{2}\right )+2 x^{2} {\mathrm e}^{\frac {x^{2}}{2}} \left (x^{2}+2\right )}\right ] \\ \end{align*}
