Galois action
Roots of defining polynomial
The roots of $f$ are computed in $\Q_{ 47 }$ to precision 5.
Roots:
| $r_{ 1 }$ | $=$ |
\( 1 + 3\cdot 47 + 44\cdot 47^{2} + 44\cdot 47^{3} + 31\cdot 47^{4} +O(47^{5})\)
|
| $r_{ 2 }$ | $=$ |
\( 4 + 31\cdot 47 + 43\cdot 47^{2} + 32\cdot 47^{3} + 29\cdot 47^{4} +O(47^{5})\)
|
| $r_{ 3 }$ | $=$ |
\( 9 + 37\cdot 47 + 17\cdot 47^{2} + 44\cdot 47^{3} + 9\cdot 47^{4} +O(47^{5})\)
|
| $r_{ 4 }$ | $=$ |
\( 33 + 22\cdot 47 + 35\cdot 47^{2} + 18\cdot 47^{3} + 22\cdot 47^{4} +O(47^{5})\)
