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:
| $r_{ 1 }$ |
$=$ |
$ 24 a + 1 + \left(19 a + 21\right)\cdot 31 + \left(25 a + 16\right)\cdot 31^{2} + \left(3 a + 12\right)\cdot 31^{3} + \left(8 a + 21\right)\cdot 31^{4} +O\left(31^{ 5 }\right)$ |
| $r_{ 2 }$ |
$=$ |
$ 7 a + 18 + \left(11 a + 5\right)\cdot 31 + \left(5 a + 17\right)\cdot 31^{2} + \left(27 a + 25\right)\cdot 31^{3} + \left(22 a + 2\right)\cdot 31^{4} +O\left(31^{ 5 }\right)$ |
| $r_{ 3 }$ |
$=$ |
$ 30 a + 7 + \left(28 a + 10\right)\cdot 31 + \left(20 a + 27\right)\cdot 31^{2} + \left(15 a + 4\right)\cdot 31^{3} + \left(22 a + 3\right)\cdot 31^{4} +O\left(31^{ 5 }\right)$ |
| $r_{ 4 }$ |
$=$ |
$ a + 5 + \left(2 a + 7\right)\cdot 31 + \left(10 a + 9\right)\cdot 31^{2} + \left(15 a + 15\right)\cdot 31^{3} + \left(8 a + 1\right)\cdot 31^{4} +O\left(31^{ 5 }\right)$ |
| $r_{ 5 }$ |
$=$ |
$ 14 + 30\cdot 31 + 2\cdot 31^{3} + 8\cdot 31^{4} +O\left(31^{ 5 }\right)$ |
| $r_{ 6 }$ |
$=$ |
