Galois action
Roots of defining polynomial
The roots of $f$ are computed in $\Q_{ 83 }$ to precision 5.
Roots:
$r_{ 1 }$ | $=$ | \( 14 + 72\cdot 83 + 51\cdot 83^{2} + 40\cdot 83^{3} + 22\cdot 83^{4} +O(83^{5})\) |
$r_{ 2 }$ | $=$ | \( 16 + 22\cdot 83 + 30\cdot 83^{2} + 34\cdot 83^{3} + 39\cdot 83^{4} +O(83^{5})\) |
$r_{ 3 }$ | $=$ | \( 61 + 47\cdot 83 + 41\cdot 83^{2} + 18\cdot 83^{3} + 45\cdot 83^{4} +O(83^{5})\) |
$r_{ 4 }$ | $=$ | \( 77 + 23\cdot 83 + 42\cdot 83^{2} + 72\cdot 83^{3} + 58\cdot 83^{4} +O(83^{5})\) |
