Defining polynomial
| $f(x)$ | $=$ |
\( x^{5} - x^{4} + x^{3} - x^{2} + 2x - 1 \)
|
The roots of $f$ are computed in an extension of $\Q_{ 23 }$ to precision 5.
Minimal polynomial of a generator $a$ of $K$ over $\mathbb{Q}_{ 23 }$:
\( x^{2} + 21x + 5 \)
Roots:
| $r_{ 1 }$ | $=$ |
\( 2 + 21\cdot 23 + 4\cdot 23^{2} + 23^{3} + 5\cdot 23^{4} +O(23^{5})\)
|
| $r_{ 2 }$ | $=$ |
\( 10 + 12\cdot 23 + 15\cdot 23^{2} + 5\cdot 23^{3} + 4\cdot 23^{4} +O(23^{5})\)
|
| $r_{ 3 }$ | $=$ |
\( 9 + 9\cdot 23 + 2\cdot 23^{2} + 11\cdot 23^{3} + 2\cdot 23^{4} +O(23^{5})\)
|
| $r_{ 4 }$ | $=$ |
\( 13 a + \left(3 a + 16\right)\cdot 23 + \left(17 a + 7\right)\cdot 23^{2} + \left(17 a + 16\right)\cdot 23^{3} + \left(9 a + 4\right)\cdot 23^{4} +O(23^{5})\)
|
| $r_{ 5 }$ | $=$ |
\( 10 a + 3 + \left(19 a + 10\right)\cdot 23 + \left(5 a + 15\right)\cdot 23^{2} + \left(5 a + 11\right)\cdot 23^{3} + \left(13 a + 6\right)\cdot 23^{4} +O(23^{5})\)
