Galois action

Roots of defining polynomial

The roots of $f$ are computed in an extension of $\Q_{ 61 }$ to precision 5.
Minimal polynomial of a generator $a$ of $K$ over $\mathbb{Q}_{ 61 }$: $ x^{2} + 60 x + 2 $
Roots:
$r_{ 1 }$ $=$ $ 9 + 40\cdot 61 + 19\cdot 61^{3} + 56\cdot 61^{4} +O\left(61^{ 5 }\right)$
$r_{ 2 }$ $=$ $ 55 a + 5 + 11\cdot 61 + \left(31 a + 18\right)\cdot 61^{2} + \left(34 a + 10\right)\cdot 61^{3} + \left(37 a + 34\right)\cdot 61^{4} +O\left(61^{ 5 }\right)$
$r_{ 3 }$ $=$ $ 10 + 59\cdot 61 + 14\cdot 61^{2} + 3\cdot 61^{3} + 24\cdot 61^{4} +O\left(61^{ 5 }\right)$
$r_{ 4 }$ $=$ $ 57 a + 52 + \left(14 a + 17\right)\cdot 61 + \left(52 a + 1\right)\cdot 61^{2} + \left(25 a + 51\right)\cdot 61^{3} + \left(21 a + 17\right)\cdot 61^{4} +O\left(61^{ 5 }\right)$
$r_{ 5 }$ $=$ $ 6 a + 60 + \left(60 a + 17\right)\cdot 61 + \left(29 a + 48\right)\cdot 61^{2} + \left(26 a + 13\right)\cdot 61^{3} + \left(23 a + 37\right)\cdot 61^{4} +O\left(61^{ 5 }\right)$
$r_{ 6 }$ $=$ $ 4 a + 48 + \left(46 a + 36\right)\cdot 61 + \left(8 a + 38\right)\cdot 61^{2} + \left(35 a + 24\right)\cdot 61^{3} + \left(39 a + 13\right)\cdot 61^{4} +O\left(61^{ 5 }\right)$
