Galois action
Roots of defining polynomial
The roots of $f$ are computed in $\Q_{ 43 }$ to precision 5.
Roots:
| $r_{ 1 }$ | $=$ |
\( 16 + 13\cdot 43 + 35\cdot 43^{2} + 32\cdot 43^{3} + 36\cdot 43^{4} +O(43^{5})\)
|
| $r_{ 2 }$ | $=$ |
\( 22 + 11\cdot 43 + 24\cdot 43^{2} + 21\cdot 43^{3} + 27\cdot 43^{4} +O(43^{5})\)
|
| $r_{ 3 }$ | $=$ |
\( 23 + 40\cdot 43 + 32\cdot 43^{2} + 31\cdot 43^{3} + 36\cdot 43^{4} +O(43^{5})\)
|
| $r_{ 4 }$ | $=$ |
\( 25 + 20\cdot 43 + 36\cdot 43^{2} + 42\cdot 43^{3} + 27\cdot 43^{4} +O(43^{5})\)
