Galois action

Roots of defining polynomial

The roots of $f$ are computed in $\Q_{ 61 }$ to precision 5.
Roots: \[ \begin{aligned} r_{ 1 } &= 114558634 +O\left(61^{ 5 }\right) \\ r_{ 2 } &= 8360685 +O\left(61^{ 5 }\right) \\ r_{ 3 } &= -8360684 +O\left(61^{ 5 }\right) \\ r_{ 4 } &= -114558633 +O\left(61^{ 5 }\right) \\ \end{aligned}\]
