Roots of defining polynomial
The roots of $f$ are computed in an extension of $\Q_{ 23 }$ to precision 5.
Minimal polynomial of a generator $a$ of $K$ over $\mathbb{Q}_{ 23 }$: $ x^{2} + 21 x + 5 $
Roots:
| $r_{ 1 }$ |
$=$ |
$ 2 + 21\cdot 23 + 4\cdot 23^{2} + 23^{3} + 5\cdot 23^{4} +O\left(23^{ 5 }\right)$ |
| $r_{ 2 }$ |
$=$ |
$ 10 + 12\cdot 23 + 15\cdot 23^{2} + 5\cdot 23^{3} + 4\cdot 23^{4} +O\left(23^{ 5 }\right)$ |
| $r_{ 3 }$ |
$=$ |
$ 9 + 9\cdot 23 + 2\cdot 23^{2} + 11\cdot 23^{3} + 2\cdot 23^{4} +O\left(23^{ 5 }\right)$ |
| $r_{ 4 }$ |
$=$ |
$ 13 a + \left(3 a + 16\right)\cdot 23 + \left(17 a + 7\right)\cdot 23^{2} + \left(17 a + 16\right)\cdot 23^{3} + \left(9 a + 4\right)\cdot 23^{4} +O\left(23^{ 5 }\right)$ |
| $r_{ 5 }$ |
$=$ |
$ 10 a + 3 + \left(19 a + 10\right)\cdot 23 + \left(5 a + 15\right)\cdot 23^{2} + \left(5 a + 11\right)\cdot 23^{3} + \left(13 a + 6\right)\cdot 23^{4} +O\left(23^{ 5 }\right)$ |
