Defining polynomial
| $f(x)$ | $=$ |
\( x^{4} - x^{3} + 176x^{2} - 176x + 6301 \)

The roots of $f$ are computed in $\Q_{ 19 }$ to precision 5.
Roots:
| $r_{ 1 }$ | $=$ |
\( 7 + 6\cdot 19 + 4\cdot 19^{2} + 11\cdot 19^{3} + 10\cdot 19^{4} +O(19^{5})\)
|
| $r_{ 2 }$ | $=$ |
\( 8 + 10\cdot 19 + 4\cdot 19^{2} + 12\cdot 19^{3} +O(19^{5})\)
|
| $r_{ 3 }$ | $=$ |
\( 10 + 19 + 5\cdot 19^{2} + 6\cdot 19^{3} + 18\cdot 19^{4} +O(19^{5})\)
|
