The roots of $f$ are computed in $\Q_{ 197 }$ to precision 5.
Roots:
| $r_{ 1 }$ | $=$ |
\( 63 + 172\cdot 197 + 28\cdot 197^{2} + 5\cdot 197^{3} + 104\cdot 197^{4} +O(197^{5})\)
|
| $r_{ 2 }$ | $=$ |
\( 65 + 25\cdot 197 + 147\cdot 197^{2} + 90\cdot 197^{3} + 101\cdot 197^{4} +O(197^{5})\)
|
| $r_{ 3 }$ | $=$ |
\( 124 + 26\cdot 197 + 107\cdot 197^{2} + 96\cdot 197^{3} + 64\cdot 197^{4} +O(197^{5})\)
|
| $r_{ 4 }$ | $=$ |
\( 142 + 169\cdot 197 + 110\cdot 197^{2} + 4\cdot 197^{3} + 124\cdot 197^{4} +O(197^{5})\)
