Roots of defining polynomial

The roots of $f$ are computed in $\Q_{ 139 }$ to precision 5.
Roots:
$r_{ 1 }$ $=$ $ 5 + 7\cdot 139 + 19\cdot 139^{2} + 56\cdot 139^{3} + 131\cdot 139^{4} +O\left(139^{ 5 }\right)$
$r_{ 2 }$ $=$ $ 19 + 73\cdot 139 + 25\cdot 139^{2} + 93\cdot 139^{3} + 78\cdot 139^{4} +O\left(139^{ 5 }\right)$
$r_{ 3 }$ $=$ $ 30 + 53\cdot 139 + 93\cdot 139^{3} + 93\cdot 139^{4} +O\left(139^{ 5 }\right)$
$r_{ 4 }$ $=$ $ 69 + 30\cdot 139 + 101\cdot 139^{2} + 94\cdot 139^{3} + 2\cdot 139^{4} +O\left(139^{ 5 }\right)$
$r_{ 5 }$ $=$ $ 95 + 87\cdot 139 + 76\cdot 139^{2} + 116\cdot 139^{3} + 56\cdot 139^{4} +O\left(139^{ 5 }\right)$
$r_{ 6 }$ $=$ $ 101 + 19\cdot 139 + 7\cdot 139^{2} + 85\cdot 139^{3} + 113\cdot 139^{4} +O\left(139^{ 5 }\right)$
$r_{ 7 }$ $=$ $ 117 + 131\cdot 139 + 83\cdot 139^{2} + 53\cdot 139^{3} + 10\cdot 139^{4} +O\left(139^{ 5 }\right)$
$r_{ 8 }$ $=$ $ 123 + 13\cdot 139 + 103\cdot 139^{2} + 102\cdot 139^{3} + 68\cdot 139^{4} +O\left(139^{ 5 }\right)$
