Defining polynomial
| $f(x)$ | $=$ |
\( x^{4} - x^{3} + 26x^{2} - 60x + 584 \)
|
The roots of $f$ are computed in $\Q_{ 181 }$ to precision 5.
Roots:
| $r_{ 1 }$ | $=$ |
\( 10 + 142\cdot 181 + 85\cdot 181^{2} + 175\cdot 181^{3} + 6\cdot 181^{4} +O(181^{5})\)
|
| $r_{ 2 }$ | $=$ |
\( 69 + 115\cdot 181 + 115\cdot 181^{2} + 40\cdot 181^{3} + 97\cdot 181^{4} +O(181^{5})\)
|
| $r_{ 3 }$ | $=$ |
\( 115 + 79\cdot 181 + 9\cdot 181^{2} + 180\cdot 181^{3} + 178\cdot 181^{4} +O(181^{5})\)
|
| $r_{ 4 }$ | $=$ |
\( 169 + 24\cdot 181 + 151\cdot 181^{2} + 146\cdot 181^{3} + 78\cdot 181^{4} +O(181^{5})\)
