Galois action
Roots of defining polynomial
The roots of $f$ are computed in $\Q_{ 47 }$ to precision 5.
Roots:
$r_{ 1 }$ | $=$ | \( 9 + 4\cdot 47 + 47^{2} + 38\cdot 47^{3} +O(47^{5})\) |
$r_{ 2 }$ | $=$ | \( 18 + 21\cdot 47 + 3\cdot 47^{2} + 26\cdot 47^{3} + 21\cdot 47^{4} +O(47^{5})\) |
$r_{ 3 }$ | $=$ | \( 31 + 31\cdot 47 + 31\cdot 47^{2} + 10\cdot 47^{3} + 19\cdot 47^{4} +O(47^{5})\) |
$r_{ 4 }$ | $=$ | \( 38 + 36\cdot 47 + 10\cdot 47^{2} + 19\cdot 47^{3} + 5\cdot 47^{4} +O(47^{5})\) |
