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 &= \left (i \sqrt {7}+4 x +1\right )^{-\frac {3}{4}+\frac {3 i \sqrt {7}}{28}} \left (i \sqrt {7}-4 x -1\right )^{-\frac {3}{4}-\frac {3 i \sqrt {7}}{28}} \left (1+x \right )\right ] \\ \left [R &= x, S \left (R \right ) &= \frac {\left (i \sqrt {7}+4 x +1\right )^{\frac {3}{4}} \left (i \sqrt {7}+4 x +1\right )^{-\frac {3 i \sqrt {7}}{28}} \left (i \sqrt {7}-4 x -1\right )^{\frac {3}{4}} \left (i \sqrt {7}-4 x -1\right )^{\frac {3 i \sqrt {7}}{28}} y}{1+x}\right ] \\ \end{align*}
