Galois action

Roots of defining polynomial

The roots of $f$ are computed in $\Q_{ 67 }$ to precision 5.
Roots:
$r_{ 1 }$ $=$ $ 37 + 60\cdot 67 + 54\cdot 67^{2} + 67^{3} + 56\cdot 67^{4} +O\left(67^{ 5 }\right)$
$r_{ 2 }$ $=$ $ 38 + 55\cdot 67 + 52\cdot 67^{2} + 5\cdot 67^{3} +O\left(67^{ 5 }\right)$
$r_{ 3 }$ $=$ $ 59 + 17\cdot 67 + 26\cdot 67^{2} + 59\cdot 67^{3} + 10\cdot 67^{4} +O\left(67^{ 5 }\right)$
