Defining polynomial
| $f(x)$ | $=$ |
\( x^{4} - 195x^{2} + 2340 \)
|
The roots of $f$ are computed in $\Q_{ 29 }$ to precision 6.
Roots:
| $r_{ 1 }$ | $=$ |
\( 1 + 5\cdot 29 + 6\cdot 29^{2} + 25\cdot 29^{3} + 13\cdot 29^{4} + 3\cdot 29^{5} +O(29^{6})\)
|
| $r_{ 2 }$ | $=$ |
\( 7 + 10\cdot 29 + 23\cdot 29^{2} + 12\cdot 29^{3} + 10\cdot 29^{4} + 26\cdot 29^{5} +O(29^{6})\)
|
| $r_{ 3 }$ | $=$ |
\( 22 + 18\cdot 29 + 5\cdot 29^{2} + 16\cdot 29^{3} + 18\cdot 29^{4} + 2\cdot 29^{5} +O(29^{6})\)
|
| $r_{ 4 }$ | $=$ |
\( 28 + 23\cdot 29 + 22\cdot 29^{2} + 3\cdot 29^{3} + 15\cdot 29^{4} + 25\cdot 29^{5} +O(29^{6})\)
