Galois action

Roots of defining polynomial

The roots of $f$ are computed in an extension of $\Q_{ 149 }$ to precision 5.
Minimal polynomial of a generator $a$ of $K$ over $\mathbb{Q}_{ 149 }$: $ x^{2} + 145 x + 2 $
Roots:
$r_{ 1 }$ $=$ $ 9 a + 105 + \left(97 a + 6\right)\cdot 149 + \left(147 a + 94\right)\cdot 149^{2} + \left(110 a + 44\right)\cdot 149^{3} + \left(14 a + 8\right)\cdot 149^{4} +O\left(149^{ 5 }\right)$
$r_{ 2 }$ $=$ $ 104 a + 8 + \left(41 a + 33\right)\cdot 149 + \left(25 a + 78\right)\cdot 149^{2} + \left(98 a + 133\right)\cdot 149^{3} + \left(97 a + 101\right)\cdot 149^{4} +O\left(149^{ 5 }\right)$
$r_{ 3 }$ $=$ $ 95 + 30\cdot 149 + 148\cdot 149^{2} + 81\cdot 149^{3} + 57\cdot 149^{4} +O\left(149^{ 5 }\right)$
$r_{ 4 }$ $=$ $ 45 a + 126 + \left(107 a + 95\right)\cdot 149 + \left(123 a + 137\right)\cdot 149^{2} + \left(50 a + 53\right)\cdot 149^{3} + \left(51 a + 96\right)\cdot 149^{4} +O\left(149^{ 5 }\right)$
$r_{ 5 }$ $=$ $ 74 + 133\cdot 149 + 118\cdot 149^{2} + 12\cdot 149^{3} + 43\cdot 149^{4} +O\left(149^{ 5 }\right)$
$r_{ 6 }$ $=$ $ 140 a + 141 + \left(51 a + 87\right)\cdot 149 + \left(a + 140\right)\cdot 149^{2} + \left(38 a + 42\right)\cdot 149^{3} + \left(134 a + 105\right)\cdot 149^{4} +O\left(149^{ 5 }\right)$
$r_{ 7 }$ $=$ $ 47 + 59\cdot 149 + 27\cdot 149^{2} + 77\cdot 149^{3} + 34\cdot 149^{4} +O\left(149^{ 5 }\right)$
