Galois action

Roots of defining polynomial

The roots of $f$ are computed in an extension of $\Q_{ 157 }$ to precision 5.
Minimal polynomial of a generator $a$ of $K$ over $\mathbb{Q}_{ 157 }$: $ x^{2} + 152 x + 5 $
Roots:
$r_{ 1 }$ $=$ $ 44 a + 15 + \left(60 a + 110\right)\cdot 157 + \left(101 a + 131\right)\cdot 157^{2} + \left(43 a + 27\right)\cdot 157^{3} + \left(77 a + 58\right)\cdot 157^{4} +O\left(157^{ 5 }\right)$
$r_{ 2 }$ $=$ $ 91 a + 98 + \left(145 a + 58\right)\cdot 157 + \left(137 a + 147\right)\cdot 157^{2} + \left(83 a + 83\right)\cdot 157^{3} + \left(36 a + 129\right)\cdot 157^{4} +O\left(157^{ 5 }\right)$
$r_{ 3 }$ $=$ $ 66 a + 82 + \left(11 a + 67\right)\cdot 157 + \left(19 a + 63\right)\cdot 157^{2} + \left(73 a + 51\right)\cdot 157^{3} + \left(120 a + 71\right)\cdot 157^{4} +O\left(157^{ 5 }\right)$
$r_{ 4 }$ $=$ $ 113 a + 78 + \left(96 a + 53\right)\cdot 157 + \left(55 a + 107\right)\cdot 157^{2} + \left(113 a + 144\right)\cdot 157^{3} + \left(79 a + 86\right)\cdot 157^{4} +O\left(157^{ 5 }\right)$
$r_{ 5 }$ $=$ $ 113 + 29\cdot 157 + 54\cdot 157^{2} + 28\cdot 157^{3} + 32\cdot 157^{4} +O\left(157^{ 5 }\right)$
$r_{ 6 }$ $=$ $ 108 a + 9 + \left(82 a + 80\right)\cdot 157 + \left(135 a + 78\right)\cdot 157^{2} + \left(55 a + 152\right)\cdot 157^{3} + \left(58 a + 6\right)\cdot 157^{4} +O\left(157^{ 5 }\right)$
$r_{ 7 }$ $=$ $ 49 a + 78 + \left(74 a + 71\right)\cdot 157 + \left(21 a + 45\right)\cdot 157^{2} + \left(101 a + 139\right)\cdot 157^{3} + \left(98 a + 85\right)\cdot 157^{4} +O\left(157^{ 5 }\right)$
