Galois action
Roots of defining polynomial
The roots of $f$ are computed in $\Q_{ 19 }$ to precision 5.
Roots:
$r_{ 1 }$ | $=$ |
\( 3 + 9\cdot 19^{2} + 7\cdot 19^{3} + 9\cdot 19^{4} +O(19^{5})\)
$r_{ 2 }$ |
$=$ |
\( 11 + 14\cdot 19 + 18\cdot 19^{3} + 12\cdot 19^{4} +O(19^{5})\)
| $r_{ 3 }$ |
$=$ |
\( 12 + 16\cdot 19 + 18\cdot 19^{2} + 15\cdot 19^{3} + 19^{4} +O(19^{5})\)
| $r_{ 4 }$ |
$=$ |
\( 13 + 6\cdot 19 + 9\cdot 19^{2} + 15\cdot 19^{3} + 13\cdot 19^{4} +O(19^{5})\)
