Roots of defining polynomial
The roots of $f$ are computed in an extension of $\Q_{ 31 }$ to precision 5.
Minimal polynomial of a generator $a$ of $K$ over $\mathbb{Q}_{ 31 }$: $ x^{2} + 29 x + 3 $
Roots:

| $r_{ 2 }$ |
$=$ |
$ 15 a + 9 + \left(30 a + 14\right)\cdot 31 + \left(8 a + 15\right)\cdot 31^{2} + \left(24 a + 22\right)\cdot 31^{3} + 12\cdot 31^{4} +O\left(31^{ 5 }\right)$ |
