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