Defining polynomial
| $f(x)$ | $=$ |
\( x^{4} - 2x^{3} - 2x - 2 \)
|
The roots of $f$ are computed in $\Q_{ 151 }$ to precision 5.
Roots:
| $r_{ 1 }$ | $=$ |
\( 21 + 60\cdot 151 + 137\cdot 151^{2} + 90\cdot 151^{3} + 81\cdot 151^{4} +O(151^{5})\)
|
| $r_{ 2 }$ | $=$ |
\( 51 + 35\cdot 151 + 116\cdot 151^{2} + 40\cdot 151^{3} +O(151^{5})\)
|
| $r_{ 3 }$ | $=$ |
\( 89 + 137\cdot 151 + 135\cdot 151^{2} + 90\cdot 151^{3} + 104\cdot 151^{4} +O(151^{5})\)
|
| $r_{ 4 }$ | $=$ |
\( 143 + 68\cdot 151 + 63\cdot 151^{2} + 79\cdot 151^{3} + 115\cdot 151^{4} +O(151^{5})\)
