Roots of defining polynomial
The roots of $f$ are computed in $\Q_{ 131 }$ to precision 5.
Roots:
| $r_{ 1 }$ |
$=$ |
$ 16 + 124\cdot 131 + 5\cdot 131^{2} + 69\cdot 131^{3} + 23\cdot 131^{4} +O\left(131^{ 5 }\right)$ |
| $r_{ 2 }$ |
$=$ |
$ 76 + 90\cdot 131 + 39\cdot 131^{2} + 120\cdot 131^{3} + 60\cdot 131^{4} +O\left(131^{ 5 }\right)$ |
| $r_{ 3 }$ |
$=$ |
$ 81 + 81\cdot 131 + 68\cdot 131^{2} + 88\cdot 131^{3} + 106\cdot 131^{4} +O\left(131^{ 5 }\right)$ |
| $r_{ 4 }$ |
$=$ |
$ 90 + 96\cdot 131 + 16\cdot 131^{2} + 115\cdot 131^{3} + 70\cdot 131^{4} +O\left(131^{ 5 }\right)$ |
