Galois action

Roots of defining polynomial

The roots of $f$ are computed in $\Q_{ 19 }$ to precision 5.
Roots:
$r_{ 1 }$ $=$ $ 6 + 6\cdot 19 + 3\cdot 19^{2} + 9\cdot 19^{3} + 5\cdot 19^{4} +O\left(19^{ 5 }\right)$
$r_{ 2 }$ $=$ $ 15 + 6\cdot 19 + 11\cdot 19^{2} + 14\cdot 19^{3} +O\left(19^{ 5 }\right)$
$r_{ 3 }$ $=$ $ 18 + 5\cdot 19 + 4\cdot 19^{2} + 14\cdot 19^{3} + 12\cdot 19^{4} +O\left(19^{ 5 }\right)$
