Roots of defining polynomial
The roots of $f$ are computed in $\Q_{ 131 }$ to precision 5.
Roots:
| $r_{ 1 }$ |
$=$ |
$ 59 + 98\cdot 131 + 38\cdot 131^{2} + 44\cdot 131^{3} + 68\cdot 131^{4} +O\left(131^{ 5 }\right)$ |
| $r_{ 2 }$ |
$=$ |
$ 84 + 106\cdot 131 + 47\cdot 131^{2} + 95\cdot 131^{3} + 15\cdot 131^{4} +O\left(131^{ 5 }\right)$ |
| $r_{ 3 }$ |
$=$ |
$ 123 + 15\cdot 131 + 53\cdot 131^{2} + 54\cdot 131^{3} + 38\cdot 131^{4} +O\left(131^{ 5 }\right)$ |
| $r_{ 4 }$ |
$=$ |
$ 128 + 40\cdot 131 + 122\cdot 131^{2} + 67\cdot 131^{3} + 8\cdot 131^{4} +O\left(131^{ 5 }\right)$ |
