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 a + 18 + \left(18 a + 5\right)\cdot 23 + \left(14 a + 3\right)\cdot 23^{2} + \left(10 a + 6\right)\cdot 23^{3} + \left(21 a + 17\right)\cdot 23^{4} +O\left(23^{ 5 }\right)$ |
| $r_{ 2 }$ |
$=$ |
$ 21 a + 22 + \left(4 a + 16\right)\cdot 23 + \left(8 a + 14\right)\cdot 23^{2} + \left(12 a + 12\right)\cdot 23^{3} + \left(a + 3\right)\cdot 23^{4} +O\left(23^{ 5 }\right)$ |
| $r_{ 3 }$ |
$=$ |
$ 4 + 14\cdot 23 + 17\cdot 23^{2} + 12\cdot 23^{3} + 23^{4} +O\left(23^{ 5 }\right)$ |
| $r_{ 4 }$ |
$=$ |
$ 19 + 20\cdot 23 + 11\cdot 23^{2} + 14\cdot 23^{3} + 5\cdot 23^{4} +O\left(23^{ 5 }\right)$ |
| $r_{ 5 }$ |
$=$ |
$ 6 + 11\cdot 23 + 21\cdot 23^{2} + 22\cdot 23^{3} + 17\cdot 23^{4} +O\left(23^{ 5 }\right)$ |
