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:
| $r_{ 1 }$ |
$=$ |
$ 17 + 26\cdot 31 + 6\cdot 31^{2} + 10\cdot 31^{3} + 3\cdot 31^{4} +O\left(31^{ 5 }\right)$ |
| $r_{ 2 }$ |
$=$ |
$ 28 a + 26 + \left(20 a + 10\right)\cdot 31 + \left(5 a + 1\right)\cdot 31^{2} + \left(18 a + 26\right)\cdot 31^{3} + \left(3 a + 3\right)\cdot 31^{4} +O\left(31^{ 5 }\right)$ |
| $r_{ 3 }$ |
$=$ |
$ 18 a + 14 + 9\cdot 31 + \left(28 a + 16\right)\cdot 31^{2} + \left(3 a + 25\right)\cdot 31^{3} + \left(5 a + 8\right)\cdot 31^{4} +O\left(31^{ 5 }\right)$ |

$ 30 + 28\cdot 31 + 4\cdot 31^{2} + 7\cdot 31^{4} +O\left(31^{ 5 }\right)$ |
| $r_{ 5 }$ |
$=$ |
$ 13 a + 19 + \left(30 a + 23\right)\cdot 31 + \left(2 a + 9\right)\cdot 31^{2} + \left(27 a + 5\right)\cdot 31^{3} + \left(25 a + 15\right)\cdot 31^{4} +O\left(31^{ 5 }\right)$ |
