  In two earlier papers it was demonstrated that Lorentzian and Galilean
symmetries could both be useful in the analysis of the annihilation reaction
$e^+ e^- \to \gamma \Lambda(\rightarrow p\pi^-) \bar{\Lambda}(\rightarrow
\bar{p}\pi^+)$. It was also demonstrated that any pair of hyperon form factors
would be acceptable, but that the $\{G_E, G_M\}$ pair would probably be the
simplest one to handle.
