     Nice, this is a computable condition! But physically we expect most modes to have the same characteristic speed $\shift{^\xi}$, resulting a algebraic multiplicity $\sim 22$, while the size of matrix is 55, then the number of minors to check is
     \begin{equation*}
-      \binom{55}{34}^2 = 708507400701023142362023505625.
+      \binom{55}{34}^2 = 708507400701023142362023505625 = 7.085\times 10^{29}.
     \end{equation*}
     It's impossible to compute so many minors.
