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:
| $r_{ 1 }$ | $=$ |
\( 4 + 11\cdot 23 + 5\cdot 23^{2} + 15\cdot 23^{3} + 14\cdot 23^{4} +O(23^{5})\)
|
| $r_{ 2 }$ | $=$ |
\( 19 a + 3 + \left(11 a + 2\right)\cdot 23 + 16\cdot 23^{2} + \left(14 a + 1\right)\cdot 23^{3} + \left(12 a + 11\right)\cdot 23^{4} +O(23^{5})\)
|
| $r_{ 3 }$ | $=$ |
\( 15 + 15\cdot 23 + 19\cdot 23^{2} + 10\cdot 23^{3} + 23^{4} +O(23^{5})\)
|
| $r_{ 4 }$ | $=$ |
\( 7 + 10\cdot 23 + 22\cdot 23^{2} + 11\cdot 23^{3} + 19\cdot 23^{4} +O(23^{5})\)
|
| $r_{ 5 }$ | $=$ |
\( 4 a + 18 + \left(11 a + 6\right)\cdot 23 + \left(22 a + 5\right)\cdot 23^{2} + \left(8 a + 6\right)\cdot 23^{3} + \left(10 a + 22\right)\cdot 23^{4} +O(23^{5})\)
