Galois action

Roots of defining polynomial

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

Generators of the action on the roots $ r_{ 1 }, r_{ 2 } $

Cycle notation
$(1,2)$
