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