Galois action

Roots of defining polynomial

The roots of $f$ are computed in $\Q_{ 67 }$ to precision 5.
Roots: \[ \begin{aligned} r_{ 1 } &= -333343750 +O\left(67^{ 5 }\right) \\ r_{ 2 } &= 293967855 +O\left(67^{ 5 }\right) \\ r_{ 3 } &= 39375896 +O\left(67^{ 5 }\right) \\ \end{aligned}\]

Generators of the action on the roots $ r_{ 1 }, r_{ 2 }, r_{ 3 } $
