Defining polynomial
| $f(x)$ | $=$ |
\( x^{4} - 2x^{3} - 8x^{2} - 8x - 1 \)
|
The roots of $f$ are computed in $\Q_{ 397 }$ to precision 5.
Roots:
| $r_{ 1 }$ | $=$ |
\( 119 + 290\cdot 397 + 197\cdot 397^{2} + 366\cdot 397^{3} + 73\cdot 397^{4} +O(397^{5})\)
|
| $r_{ 2 }$ | $=$ |
\( 160 + 173\cdot 397 + 5\cdot 397^{2} + 334\cdot 397^{3} + 381\cdot 397^{4} +O(397^{5})\)
|
| $r_{ 3 }$ | $=$ |
\( 168 + 80\cdot 397 + 249\cdot 397^{2} + 327\cdot 397^{3} + 388\cdot 397^{4} +O(397^{5})\)
|
| $r_{ 4 }$ | $=$ |
\( 349 + 249\cdot 397 + 341\cdot 397^{2} + 162\cdot 397^{3} + 346\cdot 397^{4} +O(397^{5})\)

| $6$ | $2$ | $(1,2)$ | $-1$ |
| $8$ | $3$ | $(1,2,3)$ | $0$ |
| $6$ | $4$ | $(1,2,3,4)$ | $1$ |
