Galois action
Roots of defining polynomial
The roots of $f$ are computed in $\Q_{ 167 }$ to precision 5.
Roots:
$r_{ 1 }$ | $=$ | \( 26 + 157\cdot 167 + 9\cdot 167^{2} + 155\cdot 167^{3} + 152\cdot 167^{4} +O(167^{5})\) |
$r_{ 2 }$ | $=$ | \( 38 + 67\cdot 167 + 16\cdot 167^{2} + 108\cdot 167^{3} + 130\cdot 167^{4} +O(167^{5})\) |
$r_{ 3 }$ | $=$ | \( 114 + 25\cdot 167 + 152\cdot 167^{2} + 26\cdot 167^{3} + 5\cdot 167^{4} +O(167^{5})\) |
$r_{ 4 }$ | $=$ | \( 158 + 83\cdot 167 + 155\cdot 167^{2} + 43\cdot 167^{3} + 45\cdot 167^{4} +O(167^{5})\) |
