Galois action
Roots of defining polynomial
The roots of $f$ are computed in $\Q_{ 17 }$ to precision 5.
Roots:
| $r_{ 1 }$ | $=$ |
\( 3 + 5\cdot 17 + 8\cdot 17^{2} + 7\cdot 17^{3} +O(17^{5})\)
|
| $r_{ 2 }$ | $=$ |
\( 8 + 4\cdot 17 + 12\cdot 17^{2} + 14\cdot 17^{4} +O(17^{5})\)
|
| $r_{ 3 }$ | $=$ |
\( 10 + 10\cdot 17 + 17^{2} + 11\cdot 17^{3} + 6\cdot 17^{4} +O(17^{5})\)
|
| $r_{ 4 }$ | $=$ |
\( 14 + 13\cdot 17 + 11\cdot 17^{2} + 14\cdot 17^{3} + 12\cdot 17^{4} +O(17^{5})\)
