Galois action

Roots of defining polynomial

The roots of $f$ are computed in $\Q_{ 59 }$ to precision 5.
Roots:
$r_{ 1 }$ $=$ $ 36 + 28\cdot 59 + 13\cdot 59^{2} + 12\cdot 59^{3} + 39\cdot 59^{4} +O\left(59^{ 5 }\right)$
$r_{ 2 }$ $=$ $ 39 + 47\cdot 59 + 43\cdot 59^{2} + 10\cdot 59^{3} +O\left(59^{ 5 }\right)$
$r_{ 3 }$ $=$ $ 48 + 59 + 17\cdot 59^{2} + 16\cdot 59^{3} + 10\cdot 59^{4} +O\left(59^{ 5 }\right)$
$r_{ 4 }$ $=$ $ 55 + 39\cdot 59 + 43\cdot 59^{2} + 19\cdot 59^{3} + 9\cdot 59^{4} +O\left(59^{ 5 }\right)$
