Galois action

Roots of defining polynomial

The roots of $f$ are computed in $\Q_{ 19 }$ to precision 5.
Roots:
$r_{ 1 }$ $=$ $ 6 + 18\cdot 19 + 16\cdot 19^{2} + 13\cdot 19^{3} + 10\cdot 19^{4} +O\left(19^{ 5 }\right)$
$r_{ 2 }$ $=$ $ 8 + 9\cdot 19 + 14\cdot 19^{2} + 7\cdot 19^{3} +O\left(19^{ 5 }\right)$
$r_{ 3 }$ $=$ $ 9 + 10\cdot 19 + 15\cdot 19^{2} + 10\cdot 19^{3} + 15\cdot 19^{4} +O\left(19^{ 5 }\right)$
$r_{ 4 }$ $=$ $ 15 + 18\cdot 19 + 9\cdot 19^{2} + 5\cdot 19^{3} + 11\cdot 19^{4} +O\left(19^{ 5 }\right)$
