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

The roots of $f$ are computed in $\Q_{ 79 }$ to precision 5.
Roots:
| $r_{ 1 }$ | $=$ |
\( 21 + 18\cdot 79 + 32\cdot 79^{2} + 60\cdot 79^{3} + 9\cdot 79^{4} +O(79^{5})\)
|
| $r_{ 2 }$ | $=$ |
\( 33 + 22\cdot 79 + 13\cdot 79^{2} + 5\cdot 79^{3} + 59\cdot 79^{4} +O(79^{5})\)
|
| $r_{ 3 }$ | $=$ |
\( 36 + 62\cdot 79 + 7\cdot 79^{2} + 14\cdot 79^{4} +O(79^{5})\)
|
| $r_{ 4 }$ | $=$ |
\( 69 + 54\cdot 79 + 25\cdot 79^{2} + 13\cdot 79^{3} + 75\cdot 79^{4} +O(79^{5})\)
