Galois action
Roots of defining polynomial
The roots of $f$ are computed in $\Q_{ 401 }$ to precision 5.
Roots:
| $r_{ 1 }$ | $=$ |
\( 11 + 270\cdot 401 + 222\cdot 401^{2} + 85\cdot 401^{3} + 317\cdot 401^{4} +O(401^{5})\)
|
| $r_{ 2 }$ | $=$ |
\( 92 + 174\cdot 401 + 2\cdot 401^{2} + 357\cdot 401^{3} + 342\cdot 401^{4} +O(401^{5})\)
|
| $r_{ 3 }$ | $=$ |
\( 181 + 304\cdot 401 + 218\cdot 401^{2} + 26\cdot 401^{3} + 231\cdot 401^{4} +O(401^{5})\)
|
| $r_{ 4 }$ | $=$ |
\( 191 + 11\cdot 401 + 187\cdot 401^{2} + 250\cdot 401^{3} + 93\cdot 401^{4} +O(401^{5})\)
|
| $r_{ 5 }$ | $=$ |
\( 329 + 41\cdot 401 + 171\cdot 401^{2} + 82\cdot 401^{3} + 218\cdot 401^{4} +O(401^{5})\)
