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:
$r_{ 1 }$ $=$ $ 2 a + 9 + \left(25 a + 14\right)\cdot 31 + \left(10 a + 4\right)\cdot 31^{2} + \left(10 a + 26\right)\cdot 31^{3} + \left(20 a + 25\right)\cdot 31^{4} +O\left(31^{ 5 }\right)$
$r_{ 2 }$ $=$ $ 27 + 24\cdot 31 + 22\cdot 31^{2} + 18\cdot 31^{4} +O\left(31^{ 5 }\right)$
$r_{ 3 }$ $=$ $ 27 a + \left(18 a + 6\right)\cdot 31 + \left(28 a + 22\right)\cdot 31^{2} + \left(25 a + 7\right)\cdot 31^{3} + \left(30 a + 30\right)\cdot 31^{4} +O\left(31^{ 5 }\right)$
$r_{ 4 }$ $=$ $ 4 a + 23 + \left(12 a + 16\right)\cdot 31 + \left(2 a + 29\right)\cdot 31^{2} + \left(5 a + 30\right)\cdot 31^{3} + 3\cdot 31^{4} +O\left(31^{ 5 }\right)$
$r_{ 5 }$ $=$ $ 24 a + 2 + \left(19 a + 23\right)\cdot 31 + \left(5 a + 10\right)\cdot 31^{2} + \left(26 a + 3\right)\cdot 31^{3} + \left(24 a + 14\right)\cdot 31^{4} +O\left(31^{ 5 }\right)$
$r_{ 6 }$ $=$ $ 7 a + 19 + \left(11 a + 7\right)\cdot 31 + \left(25 a + 2\right)\cdot 31^{2} + \left(4 a + 19\right)\cdot 31^{3} + \left(6 a + 6\right)\cdot 31^{4} +O\left(31^{ 5 }\right)$
$r_{ 7 }$ $=$ $ 29 a + 13 + 5 a\cdot 31 + \left(20 a + 1\right)\cdot 31^{2} + \left(20 a + 5\right)\cdot 31^{3} + \left(10 a + 25\right)\cdot 31^{4} +O\left(31^{ 5 }\right)$
