Roots of defining polynomial
The roots of $f$ are computed in $\Q_{ 31 }$ to precision 5.
Roots:
| $r_{ 1 }$ |
$=$ |
$ 4 + 31 + 19\cdot 31^{2} + 25\cdot 31^{3} + 12\cdot 31^{4} +O\left(31^{ 5 }\right)$ |
| $r_{ 2 }$ |
$=$ |
$ 14 + 5\cdot 31 + 30\cdot 31^{2} + 25\cdot 31^{3} + 8\cdot 31^{4} +O\left(31^{ 5 }\right)$ |
| $r_{ 3 }$ |
$=$ |
$ 17 + 25\cdot 31 + 5\cdot 31^{3} + 22\cdot 31^{4} +O\left(31^{ 5 }\right)$ |
| $r_{ 4 }$ |
$=$ |
$ 27 + 29\cdot 31 + 11\cdot 31^{2} + 5\cdot 31^{3} + 18\cdot 31^{4} +O\left(31^{ 5 }\right)$ |
Generators of the action on the roots
