Galois action
Roots of defining polynomial
The roots of $f$ are computed in $\Q_{ 71 }$ to precision 5.
Roots:
| $r_{ 1 }$ | $=$ |
\( 43 + 66\cdot 71 + 34\cdot 71^{2} + 71^{3} + 27\cdot 71^{4} +O(71^{5})\)
|
| $r_{ 2 }$ | $=$ |
\( 50 + 68\cdot 71 + 69\cdot 71^{2} + 32\cdot 71^{3} + 4\cdot 71^{4} +O(71^{5})\)
|
| $r_{ 3 }$ | $=$ |
\( 55 + 14\cdot 71 + 52\cdot 71^{2} + 37\cdot 71^{3} + 13\cdot 71^{4} +O(71^{5})\)
|
| $r_{ 4 }$ | $=$ |
\( 66 + 62\cdot 71 + 55\cdot 71^{2} + 69\cdot 71^{3} + 25\cdot 71^{4} +O(71^{5})\)
