Galois action

Roots of defining polynomial

The roots of $f$ are computed in an extension of $\Q_{ 31 }$ to precision 5.
Minimal polynomial of a generator $a$ of $K$ over $\mathbb{Q}_{ 31 }$: $ x^{2} + 29 x + 3 $
Roots:
$r_{ 1 }$ $=$ $ 1 + 4\cdot 31 + 15\cdot 31^{3} + 13\cdot 31^{4} +O\left(31^{ 5 }\right)$
$r_{ 2 }$ $=$ $ 9 a + 18 + \left(26 a + 20\right)\cdot 31 + \left(30 a + 10\right)\cdot 31^{2} + \left(a + 9\right)\cdot 31^{3} + \left(3 a + 24\right)\cdot 31^{4} +O\left(31^{ 5 }\right)$
$r_{ 3 }$ $=$ $ 20 a + 13 + \left(15 a + 4\right)\cdot 31 + \left(21 a + 19\right)\cdot 31^{2} + \left(21 a + 18\right)\cdot 31^{3} + \left(28 a + 18\right)\cdot 31^{4} +O\left(31^{ 5 }\right)$
$r_{ 4 }$ $=$ $ 4 + 15\cdot 31 + 31^{2} + 27\cdot 31^{3} + 15\cdot 31^{4} +O\left(31^{ 5 }\right)$
$r_{ 5 }$ $=$ $ 11 a + 22 + \left(15 a + 15\right)\cdot 31 + \left(9 a + 15\right)\cdot 31^{2} + \left(9 a + 9\right)\cdot 31^{3} + \left(2 a + 23\right)\cdot 31^{4} +O\left(31^{ 5 }\right)$
$r_{ 6 }$ $=$ $ 22 a + 5 + \left(4 a + 2\right)\cdot 31 + 15\cdot 31^{2} + \left(29 a + 13\right)\cdot 31^{3} + \left(27 a + 28\right)\cdot 31^{4} +O\left(31^{ 5 }\right)$
