Roots of defining polynomial
The roots of $f$ are computed in $\Q_{ 19 }$ to precision 5.
Roots:
| $r_{ 1 }$ |
$=$ |
$ 6 + 14\cdot 19 + 9\cdot 19^{2} + 8\cdot 19^{3} + 11\cdot 19^{4} +O\left(19^{ 5 }\right)$ |
| $r_{ 2 }$ |
$=$ |
$ 15 + 13\cdot 19 + 9\cdot 19^{2} + 3\cdot 19^{3} + 3\cdot 19^{4} +O\left(19^{ 5 }\right)$ |
| $r_{ 3 }$ |
$=$ |
$ 18 + 9\cdot 19 + 18\cdot 19^{2} + 6\cdot 19^{3} + 4\cdot 19^{4} +O\left(19^{ 5 }\right)$ |
Generators of the action on the roots
$ r_{ 1 }, r_{ 2 }, r_{ 3 } $
| Cycle notation |
