Roots of defining polynomial
The roots of $f$ are computed in an extension of $\Q_{ 41 }$ to precision 5.
Minimal polynomial of a generator $a$ of $K$ over $\mathbb{Q}_{ 41 }$: $ x^{2} + 38 x + 6 $
Roots:
| $r_{ 1 }$ |
$=$ |
$ 9 a + 9 + \left(38 a + 13\right)\cdot 41 + \left(31 a + 18\right)\cdot 41^{2} + \left(13 a + 16\right)\cdot 41^{3} + \left(25 a + 1\right)\cdot 41^{4} +O\left(41^{ 5 }\right)$ |
| $r_{ 2 }$ |
$=$ |
$ 14 a + 33 + \left(8 a + 2\right)\cdot 41 + \left(26 a + 12\right)\cdot 41^{2} + \left(40 a + 35\right)\cdot 41^{3} + \left(37 a + 22\right)\cdot 41^{4} +O\left(41^{ 5 }\right)$ |
| $r_{ 3 }$ |
$=$ |
$ 27 a + 34 + \left(32 a + 13\right)\cdot 41 + 14 a\cdot 41^{2} + 8\cdot 41^{3} + \left(3 a + 14\right)\cdot 41^{4} +O\left(41^{ 5 }\right)$ |
| $r_{ 4 }$ |
$=$ |
$ 32 a + 36 + \left(2 a + 36\right)\cdot 41 + \left(9 a + 34\right)\cdot 41^{2} + \left(27 a + 25\right)\cdot 41^{3} + \left(15 a + 22\right)\cdot 41^{4} +O\left(41^{ 5 }\right)$ |
| $r_{ 5 }$ |
$=$ |
