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:
| $r_{ 1 }$ |
$=$ |
$ 4 + 19\cdot 23 + 17\cdot 23^{2} + 5\cdot 23^{3} + 8\cdot 23^{4} +O\left(23^{ 5 }\right)$ |
| $r_{ 2 }$ |
$=$ |
$ 9 a + 12 + \left(18 a + 5\right)\cdot 23 + \left(13 a + 4\right)\cdot 23^{2} + \left(10 a + 6\right)\cdot 23^{3} + \left(4 a + 10\right)\cdot 23^{4} +O\left(23^{ 5 }\right)$ |
| $r_{ 3 }$ |
$=$ |
$ 11 + 18\cdot 23 + 2\cdot 23^{2} + 13\cdot 23^{3} + 10\cdot 23^{4} +O\left(23^{ 5 }\right)$ |
| $r_{ 4 }$ |
$=$ |
$ 14 a + 7 + \left(4 a + 10\right)\cdot 23 + \left(9 a + 13\right)\cdot 23^{2} + \left(12 a + 13\right)\cdot 23^{3} + \left(18 a + 8\right)\cdot 23^{4} +O\left(23^{ 5 }\right)$ |
| $r_{ 5 }$ |
$=$ |
$ 14 + 15\cdot 23 + 7\cdot 23^{2} + 7\cdot 23^{3} + 8\cdot 23^{4} +O\left(23^{ 5 }\right)$ |
