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