Galois action

Roots of defining polynomial

The roots of $f$ are computed in $\Q_{ 11 }$ to precision 6.
Roots:
$r_{ 1 }$ $=$ $ 1 + 5\cdot 11 + 3\cdot 11^{4} + 9\cdot 11^{5} +O\left(11^{ 6 }\right)$
$r_{ 2 }$ $=$ $ 3 + 6\cdot 11 + 5\cdot 11^{2} + 9\cdot 11^{3} + 10\cdot 11^{5} +O\left(11^{ 6 }\right)$
$r_{ 3 }$ $=$ $ 5 + 9\cdot 11 + 7\cdot 11^{2} + 10\cdot 11^{3} + 11^{4} +O\left(11^{ 6 }\right)$
$r_{ 4 }$ $=$ $ 6 + 8\cdot 11 + 5\cdot 11^{2} + 9\cdot 11^{3} + 2\cdot 11^{4} + 6\cdot 11^{5} +O\left(11^{ 6 }\right)$
$r_{ 5 }$ $=$ $ 8 + 3\cdot 11 + 2\cdot 11^{2} + 3\cdot 11^{3} + 2\cdot 11^{4} + 7\cdot 11^{5} +O\left(11^{ 6 }\right)$
