Galois action

Roots of defining polynomial

The roots of $f$ are computed in $\Q_{ 31 }$ to precision 5.
Roots: \[ \begin{aligned} r_{ 1 } &= 4017795 +O\left(31^{ 5 }\right) \\ r_{ 2 } &= -11404298 +O\left(31^{ 5 }\right) \\ r_{ 3 } &= -1955492 +O\left(31^{ 5 }\right) \\ r_{ 4 } &= 9341996 +O\left(31^{ 5 }\right) \\ \end{aligned}\]
