Galois action
Roots of defining polynomial
The roots of $f$ are computed in $\Q_{ 61 }$ to precision 5.
Roots:
| $r_{ 1 }$ | $=$ |
\( 27 + 21\cdot 61 + 25\cdot 61^{2} + 29\cdot 61^{3} + 54\cdot 61^{4} +O(61^{5})\)
|
| $r_{ 2 }$ | $=$ |
\( 39 + 12\cdot 61 + 61^{2} + 22\cdot 61^{3} + 33\cdot 61^{4} +O(61^{5})\)
|
| $r_{ 3 }$ | $=$ |
\( 57 + 26\cdot 61 + 34\cdot 61^{2} + 9\cdot 61^{3} + 34\cdot 61^{4} +O(61^{5})\)
