Galois action
Roots of defining polynomial
The roots of $f$ are computed in $\Q_{ 41 }$ to precision 5.
Roots:
| $r_{ 1 }$ | $=$ |
\( 7 + 8\cdot 41 + 6\cdot 41^{2} + 6\cdot 41^{3} + 41^{4} +O(41^{5})\)
|
| $r_{ 2 }$ | $=$ |
\( 19 + 2\cdot 41 + 17\cdot 41^{2} + 33\cdot 41^{3} + 13\cdot 41^{4} +O(41^{5})\)
|
| $r_{ 3 }$ | $=$ |
\( 27 + 8\cdot 41 + 20\cdot 41^{2} + 32\cdot 41^{3} + 14\cdot 41^{4} +O(41^{5})\)
|
| $r_{ 4 }$ | $=$ |
\( 29 + 21\cdot 41 + 38\cdot 41^{2} + 9\cdot 41^{3} + 11\cdot 41^{4} +O(41^{5})\)
