Galois action

Roots of defining polynomial

The roots of $f$ are computed in $\Q_{ 59 }$ to precision 5.
Roots:
$r_{ 1 }$ $=$ $ 14\cdot 59 + 15\cdot 59^{2} + 21\cdot 59^{3} + 19\cdot 59^{4} +O\left(59^{ 5 }\right)$
$r_{ 2 }$ $=$ $ 19 + 56\cdot 59^{2} + 57\cdot 59^{3} + 17\cdot 59^{4} +O\left(59^{ 5 }\right)$
$r_{ 3 }$ $=$ $ 48 + 54\cdot 59 + 59^{2} + 28\cdot 59^{3} + 47\cdot 59^{4} +O\left(59^{ 5 }\right)$
$r_{ 4 }$ $=$ $ 52 + 48\cdot 59 + 44\cdot 59^{2} + 10\cdot 59^{3} + 33\cdot 59^{4} +O\left(59^{ 5 }\right)$
