Defining polynomial
| $f(x)$ | $=$ |
\( x^{5} - 2x^{4} + 2x^{3} - 2x^{2} - 1 \)
|
The roots of $f$ are computed in an extension of $\Q_{ 43 }$ to precision 5.
Minimal polynomial of a generator $a$ of $K$ over $\mathbb{Q}_{ 43 }$:
\( x^{2} + 42x + 3 \)
Roots:
| $r_{ 1 }$ | $=$ |
\( 28 + 40\cdot 43 + 38\cdot 43^{2} + 29\cdot 43^{3} + 14\cdot 43^{4} +O(43^{5})\)
|
| $r_{ 2 }$ | $=$ |
\( 24 a + 41 + \left(22 a + 6\right)\cdot 43 + \left(11 a + 39\right)\cdot 43^{2} + \left(14 a + 10\right)\cdot 43^{3} + \left(33 a + 1\right)\cdot 43^{4} +O(43^{5})\)
|
| $r_{ 3 }$ | $=$ |
\( 22 + 4\cdot 43 + 12\cdot 43^{2} + 42\cdot 43^{3} +O(43^{5})\)
