Defining polynomial
| $f(x)$ | $=$ |
\( x^{4} - x^{3} - x^{2} - 2x + 1 \)
|
The roots of $f$ are computed in $\Q_{ 313 }$ to precision 5.
Roots:
| $r_{ 1 }$ | $=$ |
\( 166 + 201\cdot 313 + 6\cdot 313^{2} + 25\cdot 313^{3} + 242\cdot 313^{4} +O(313^{5})\)
|
| $r_{ 2 }$ | $=$ |
\( 196 + 298\cdot 313 + 173\cdot 313^{2} + 281\cdot 313^{3} + 231\cdot 313^{4} +O(313^{5})\)
|
| $r_{ 3 }$ | $=$ |
\( 269 + 292\cdot 313 + 37\cdot 313^{2} + 307\cdot 313^{3} + 247\cdot 313^{4} +O(313^{5})\)
|
| $r_{ 4 }$ | $=$ |
\( 309 + 145\cdot 313 + 94\cdot 313^{2} + 12\cdot 313^{3} + 217\cdot 313^{4} +O(313^{5})\)
