Roots of defining polynomial
The roots of $f$ are computed in $\Q_{ 421 }$ to precision 5.
Roots:
| $r_{ 1 }$ |
$=$ |
$ 255 + 39\cdot 421 + 198\cdot 421^{2} + 283\cdot 421^{3} + 158\cdot 421^{4} +O\left(421^{ 5 }\right)$ |
| $r_{ 2 }$ |
$=$ |
$ 273 + 68\cdot 421 + 414\cdot 421^{2} + 411\cdot 421^{3} + 368\cdot 421^{4} +O\left(421^{ 5 }\right)$ |
| $r_{ 3 }$ |
$=$ |
$ 362 + 23\cdot 421 + 336\cdot 421^{2} + 75\cdot 421^{3} + 132\cdot 421^{4} +O\left(421^{ 5 }\right)$ |
| $r_{ 4 }$ |
$=$ |
$ 374 + 288\cdot 421 + 314\cdot 421^{2} + 70\cdot 421^{3} + 182\cdot 421^{4} +O\left(421^{ 5 }\right)$ |
