Roots of defining polynomial
The roots of $f$ are computed in an extension of $\Q_{ 17 }$ to precision 5.
Minimal polynomial of a generator $a$ of $K$ over $\mathbb{Q}_{ 17 }$: $ x^{2} + 16 x + 3 $
Roots:
| $r_{ 1 }$ |
$=$ |
$ 10 a + 2 + \left(14 a + 2\right)\cdot 17 + \left(15 a + 14\right)\cdot 17^{2} + \left(6 a + 16\right)\cdot 17^{3} + \left(7 a + 8\right)\cdot 17^{4} +O\left(17^{ 5 }\right)$ |
| $r_{ 2 }$ |
$=$ |
$ a + 9 + \left(5 a + 13\right)\cdot 17 + \left(15 a + 8\right)\cdot 17^{2} + \left(8 a + 6\right)\cdot 17^{3} + \left(11 a + 8\right)\cdot 17^{4} +O\left(17^{ 5 }\right)$ |
| $r_{ 3 }$ |
$=$ |
$ 16 a + 10 + 11 a\cdot 17 + \left(a + 2\right)\cdot 17^{2} + 8 a\cdot 17^{3} + \left(5 a + 11\right)\cdot 17^{4} +O\left(17^{ 5 }\right)$ |
| $r_{ 4 }$ |
$=$ |
$ 2 + 11\cdot 17 + 10\cdot 17^{2} + 2\cdot 17^{3} + 13\cdot 17^{4} +O\left(17^{ 5 }\right)$ |
| $r_{ 5 }$ |
$=$ |
$ 7 a + 12 + \left(2 a + 6\right)\cdot 17 + \left(a + 15\right)\cdot 17^{2} + \left(10 a + 7\right)\cdot 17^{3} + \left(9 a + 9\right)\cdot 17^{4} +O\left(17^{ 5 }\right)$ |
