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:
| $r_{ 1 }$ |
$=$ |
$ 5 a + 31 + \left(36 a + 36\right)\cdot 41 + \left(33 a + 32\right)\cdot 41^{2} + \left(15 a + 6\right)\cdot 41^{3} + \left(12 a + 36\right)\cdot 41^{4} +O\left(41^{ 5 }\right)$ |
| $r_{ 2 }$ |
$=$ |
$ 36 a + 5 + \left(4 a + 17\right)\cdot 41 + \left(7 a + 16\right)\cdot 41^{2} + \left(25 a + 20\right)\cdot 41^{3} + \left(28 a + 16\right)\cdot 41^{4} +O\left(41^{ 5 }\right)$ |
| $r_{ 3 }$ |
$=$ |
$ 32 + 3\cdot 41 + 31\cdot 41^{2} + 22\cdot 41^{3} + 36\cdot 41^{4} +O\left(41^{ 5 }\right)$ |
| $r_{ 4 }$ |
$=$ |
$ 33 + 15\cdot 41 + 13\cdot 41^{2} + 29\cdot 41^{3} + 19\cdot 41^{4} +O\left(41^{ 5 }\right)$ |
| $r_{ 5 }$ |
$=$ |
$ 23 + 8\cdot 41 + 29\cdot 41^{2} + 2\cdot 41^{3} + 14\cdot 41^{4} +O\left(41^{ 5 }\right)$ |
