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