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 $\mathbb{Q}_{ 17 }$:
\( x^{2} + 16x + 3 \)
Roots:
$r_{ 1 }$ | $=$ |
\( 3 + 17 + 13\cdot 17^{2} + 17^{3} + 17^{4} + 11\cdot 17^{5} +O(17^{6})\)
$r_{ 2 }$ |
$=$ |
\( 6 a + 15 + \left(12 a + 12\right)\cdot 17 + \left(12 a + 15\right)\cdot 17^{2} + \left(10 a + 10\right)\cdot 17^{3} + 10 a\cdot 17^{4} + \left(4 a + 12\right)\cdot 17^{5} +O(17^{6})\)
| $r_{ 3 }$ |
$=$ |
\( 3 a + 13 + 2 a\cdot 17 + \left(12 a + 15\right)\cdot 17^{2} + \left(8 a + 7\right)\cdot 17^{3} + \left(a + 2\right)\cdot 17^{4} + \left(a + 11\right)\cdot 17^{5} +O(17^{6})\)
| $r_{ 4 }$ |
$=$ |
\( 14 a + 16 + \left(14 a + 16\right)\cdot 17 + \left(4 a + 7\right)\cdot 17^{2} + \left(8 a + 4\right)\cdot 17^{3} + \left(15 a + 12\right)\cdot 17^{4} + \left(15 a + 10\right)\cdot 17^{5} +O(17^{6})\)
| $r_{ 5 }$ |
$=$ |
\( 11 a + 4 + \left(4 a + 2\right)\cdot 17 + \left(4 a + 16\right)\cdot 17^{2} + \left(6 a + 8\right)\cdot 17^{3} + 6 a\cdot 17^{4} + \left(12 a + 6\right)\cdot 17^{5} +O(17^{6})\)
