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:
| $r_{ 1 }$ |
$=$ |
$ 26 a + 1 + 9 a\cdot 41 + \left(6 a + 26\right)\cdot 41^{2} + 16 a\cdot 41^{3} + \left(4 a + 35\right)\cdot 41^{4} +O\left(41^{ 5 }\right)$ |
| $r_{ 2 }$ |
$=$ |
$ 25 + 5\cdot 41 + 18\cdot 41^{2} + 30\cdot 41^{3} + 23\cdot 41^{4} +O\left(41^{ 5 }\right)$ |
| $r_{ 3 }$ |
$=$ |
$ 12 a + 32 + \left(21 a + 10\right)\cdot 41 + \left(32 a + 4\right)\cdot 41^{2} + \left(38 a + 3\right)\cdot 41^{3} + \left(31 a + 8\right)\cdot 41^{4} +O\left(41^{ 5 }\right)$ |

$ 15 a + 38 + \left(31 a + 2\right)\cdot 41 + \left(34 a + 35\right)\cdot 41^{2} + \left(24 a + 1\right)\cdot 41^{3} + \left(36 a + 32\right)\cdot 41^{4} +O\left(41^{ 5 }\right)$ |
| $r_{ 5 }$ |
$=$ |
