Galois action

Roots of defining polynomial

The roots of $f$ are computed in $\Q_{ 19 }$ to precision 5.
Roots:
$r_{ 1 }$ $=$ $ 11\cdot 19 + 18\cdot 19^{2} + 2\cdot 19^{3} + 12\cdot 19^{4} +O\left(19^{ 5 }\right)$
$r_{ 2 }$ $=$ $ 1 + 2\cdot 19 + 18\cdot 19^{2} + 8\cdot 19^{3} + 11\cdot 19^{4} +O\left(19^{ 5 }\right)$
$r_{ 3 }$ $=$ $ 5 + 10\cdot 19 + 10\cdot 19^{2} + 11\cdot 19^{3} + 14\cdot 19^{4} +O\left(19^{ 5 }\right)$
$r_{ 4 }$ $=$ $ 14 + 14\cdot 19 + 9\cdot 19^{2} + 14\cdot 19^{3} + 18\cdot 19^{4} +O\left(19^{ 5 }\right)$
