Roots of defining polynomial
The roots of $f$ are computed in $\Q_{ 13 }$ to precision 6.
Roots:
| $r_{ 1 }$ |
$=$ |
$ 7\cdot 13 + 11\cdot 13^{2} + 3\cdot 13^{3} + 13^{4} + 4\cdot 13^{5} +O\left(13^{ 6 }\right)$ |
| $r_{ 2 }$ |
$=$ |
$ 2 + 12\cdot 13 + 10\cdot 13^{3} + 4\cdot 13^{4} + 9\cdot 13^{5} +O\left(13^{ 6 }\right)$ |
| $r_{ 3 }$ |
$=$ |
$ 5 + 13 + 8\cdot 13^{2} + 4\cdot 13^{3} + 11\cdot 13^{4} + 11\cdot 13^{5} +O\left(13^{ 6 }\right)$ |
| $r_{ 4 }$ |
$=$ |
$ 8 + 5\cdot 13 + 5\cdot 13^{2} + 7\cdot 13^{3} + 8\cdot 13^{4} +O\left(13^{ 6 }\right)$ |
