Roots of defining polynomial

The roots of $f$ are computed in $\Q_{ 59 }$ to precision 5.
Roots:
$r_{ 1 }$ $=$ $ 3 + 24\cdot 59 + 53\cdot 59^{2} + 13\cdot 59^{3} + 7\cdot 59^{4} +O\left(59^{ 5 }\right)$
$r_{ 2 }$ $=$ $ 12 + 27\cdot 59 + 41\cdot 59^{2} + 22\cdot 59^{3} + 27\cdot 59^{4} +O\left(59^{ 5 }\right)$
$r_{ 3 }$ $=$ $ 22 + 46\cdot 59 + 47\cdot 59^{2} + 16\cdot 59^{3} + 57\cdot 59^{4} +O\left(59^{ 5 }\right)$
$r_{ 4 }$ $=$ $ 25 + 3\cdot 59 + 35\cdot 59^{2} + 29\cdot 59^{3} + 13\cdot 59^{4} +O\left(59^{ 5 }\right)$
$r_{ 5 }$ $=$ $ 27 + 20\cdot 59^{2} + 28\cdot 59^{3} + 20\cdot 59^{4} +O\left(59^{ 5 }\right)$
$r_{ 6 }$ $=$ $ 44 + 5\cdot 59 + 20\cdot 59^{3} + 39\cdot 59^{4} +O\left(59^{ 5 }\right)$
$r_{ 7 }$ $=$ $ 49 + 6\cdot 59 + 42\cdot 59^{2} + 8\cdot 59^{3} + 14\cdot 59^{4} +O\left(59^{ 5 }\right)$
$r_{ 8 }$ $=$ $ 55 + 3\cdot 59 + 55\cdot 59^{2} + 36\cdot 59^{3} + 56\cdot 59^{4} +O\left(59^{ 5 }\right)$
