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} + 18 x + 2 $
Roots:

| $r_{ 2 }$ |
$=$ |
$ 10 a + 12 + 18 a\cdot 19 + \left(a + 12\right)\cdot 19^{2} + \left(10 a + 3\right)\cdot 19^{3} + \left(9 a + 3\right)\cdot 19^{4} +O\left(19^{ 5 }\right)$ |
