Galois action
Roots of defining polynomial
The roots of $f$ are computed in $\Q_{ 83 }$ to precision 5.
Roots:
| $r_{ 1 }$ | $=$ |
\( 18 + 49\cdot 83 + 18\cdot 83^{2} + 81\cdot 83^{3} + 54\cdot 83^{4} +O(83^{5})\)
|
| $r_{ 2 }$ | $=$ |
\( 19 + 19\cdot 83 + 52\cdot 83^{2} + 3\cdot 83^{3} + 37\cdot 83^{4} +O(83^{5})\)
|
| $r_{ 3 }$ | $=$ |
\( 56 + 52\cdot 83 + 29\cdot 83^{2} + 48\cdot 83^{3} + 62\cdot 83^{4} +O(83^{5})\)
|
| $r_{ 4 }$ | $=$ |
\( 74 + 44\cdot 83 + 65\cdot 83^{2} + 32\cdot 83^{3} + 11\cdot 83^{4} +O(83^{5})\)
