\( x^{4} - x - 1 \)

The roots of $f$ are computed in $\Q_{ 83 }$ to precision 5.
Roots:
| $r_{ 1 }$ | $=$ |
\( 24 + 9\cdot 83 + 12\cdot 83^{2} + 54\cdot 83^{3} + 39\cdot 83^{4} +O(83^{5})\)
|
| $r_{ 2 }$ | $=$ |
\( 69 + 25\cdot 83 + 54\cdot 83^{2} + 79\cdot 83^{3} + 27\cdot 83^{4} +O(83^{5})\)
|
| $r_{ 3 }$ | $=$ |
\( 76 + 31\cdot 83 + 31\cdot 83^{2} + 20\cdot 83^{3} + 46\cdot 83^{4} +O(83^{5})\)
|
| $r_{ 4 }$ | $=$ |
\( 80 + 15\cdot 83 + 68\cdot 83^{2} + 11\cdot 83^{3} + 52\cdot 83^{4} +O(83^{5})\)
