Galois action

Roots of defining polynomial

The roots of $f$ are computed in $\Q_{ 17 }$ to precision 5.
Roots:
$r_{ 1 }$ $=$ $ 6 + 7\cdot 17^{2} + 17^{3} + 10\cdot 17^{4} +O\left(17^{ 5 }\right)$
$r_{ 2 }$ $=$ $ 11 + 16\cdot 17 + 9\cdot 17^{2} + 15\cdot 17^{3} + 6\cdot 17^{4} +O\left(17^{ 5 }\right)$

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