Galois action
Roots of defining polynomial
The roots of $f$ are computed in $\Q_{ 19 }$ to precision 5.
Roots:
| $r_{ 1 }$ | $=$ |
\( 3 + 4\cdot 19 + 6\cdot 19^{2} + 19^{4} +O(19^{5})\)
|
| $r_{ 2 }$ | $=$ |
\( 4 + 15\cdot 19 + 14\cdot 19^{2} + 18\cdot 19^{3} +O(19^{5})\)
|
| $r_{ 3 }$ | $=$ |
\( 14 + 10\cdot 19^{2} + 19^{3} + 12\cdot 19^{4} +O(19^{5})\)
|
| $r_{ 4 }$ | $=$ |
\( 18 + 17\cdot 19 + 6\cdot 19^{2} + 17\cdot 19^{3} + 4\cdot 19^{4} +O(19^{5})\)
