Galois action
Roots of defining polynomial
The roots of $f$ are computed in an extension of $\Q_{ 19 }$ to precision 5.
Minimal polynomial of a generator $a$ of $K$ over $\mathbb{Q}_{ 19 }$:
\( x^{2} + 18x + 2 \)

\( 16 + 12\cdot 19 + 6\cdot 19^{2} + 9\cdot 19^{3} + 7\cdot 19^{4} +O(19^{5})\)
|
| $r_{ 2 }$ | $=$ |
\( 13 + 9\cdot 19 + 16\cdot 19^{2} + 11\cdot 19^{4} +O(19^{5})\)
