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