Galois action

Roots of defining polynomial

The roots of $f$ are computed in $\Q_{ 19 }$ to precision 5.
Roots:
$r_{ 1 }$ $=$ $ 4 + 19 + 9\cdot 19^{2} + 19^{4} +O\left(19^{ 5 }\right)$
$r_{ 2 }$ $=$ $ 8 + 15\cdot 19 + 2\cdot 19^{2} + 19^{3} + 16\cdot 19^{4} +O\left(19^{ 5 }\right)$
$r_{ 3 }$ $=$ $ 13 + 17\cdot 19 + 19^{2} + 16\cdot 19^{3} + 5\cdot 19^{4} +O\left(19^{ 5 }\right)$
$r_{ 4 }$ $=$ $ 14 + 3\cdot 19 + 5\cdot 19^{2} + 19^{3} + 15\cdot 19^{4} +O\left(19^{ 5 }\right)$
