Galois action

Roots of defining polynomial

The roots of $f$ are computed in $\Q_{ 7 }$ to precision 5.
Roots:
$r_{ 1 }$ $=$ $ 1 + 5\cdot 7 + 2\cdot 7^{2} + 7^{3} + 5\cdot 7^{4} +O\left(7^{ 5 }\right)$
$r_{ 2 }$ $=$ $ 3 + 6\cdot 7 + 2\cdot 7^{2} + 3\cdot 7^{3} + 2\cdot 7^{4} +O\left(7^{ 5 }\right)$
$r_{ 3 }$ $=$ $ 4 + 2\cdot 7 + 7^{2} + 2\cdot 7^{3} + 6\cdot 7^{4} +O\left(7^{ 5 }\right)$
