Defining polynomial
| $f(x)$ | $=$ |
\( x^{4} - x^{3} + x^{2} - 2x - 1 \)
|
The roots of $f$ are computed in $\Q_{ 61 }$ to precision 5.
Roots:
| $r_{ 1 }$ | $=$ |
\( 23 + 35\cdot 61 + 48\cdot 61^{2} + 3\cdot 61^{3} + 49\cdot 61^{4} +O(61^{5})\)
|
| $r_{ 2 }$ | $=$ |
\( 49 + 54\cdot 61 + 56\cdot 61^{2} + 36\cdot 61^{3} + 28\cdot 61^{4} +O(61^{5})\)
|
| $r_{ 3 }$ | $=$ |
\( 54 + 28\cdot 61 + 47\cdot 61^{2} + 10\cdot 61^{3} + 20\cdot 61^{4} +O(61^{5})\)
|
| $r_{ 4 }$ | $=$ |
\( 58 + 2\cdot 61 + 30\cdot 61^{2} + 9\cdot 61^{3} + 24\cdot 61^{4} +O(61^{5})\)
