Galois action

Roots of defining polynomial

The roots of $f$ are computed in an extension of $\Q_{ 37 }$ to precision 5.
Minimal polynomial of a generator $a$ of $K$ over $\mathbb{Q}_{ 37 }$: $ x^{2} + 33 x + 2 $
Roots:
$r_{ 1 }$ $=$ $ 24 a + 9 + \left(26 a + 1\right)\cdot 37 + \left(19 a + 33\right)\cdot 37^{2} + \left(22 a + 27\right)\cdot 37^{3} + \left(6 a + 27\right)\cdot 37^{4} +O\left(37^{ 5 }\right)$
$r_{ 2 }$ $=$ $ 13 a + 31 + \left(10 a + 9\right)\cdot 37 + \left(17 a + 11\right)\cdot 37^{2} + \left(14 a + 24\right)\cdot 37^{3} + \left(30 a + 31\right)\cdot 37^{4} +O\left(37^{ 5 }\right)$
$r_{ 3 }$ $=$ $ 32 a + 19 + \left(24 a + 23\right)\cdot 37 + 15\cdot 37^{2} + \left(23 a + 3\right)\cdot 37^{3} + \left(13 a + 35\right)\cdot 37^{4} +O\left(37^{ 5 }\right)$
$r_{ 4 }$ $=$ $ 6 + 31\cdot 37 + 33\cdot 37^{2} + 14\cdot 37^{3} + 34\cdot 37^{4} +O\left(37^{ 5 }\right)$
$r_{ 5 }$ $=$ $ 12 + 28\cdot 37 + 23\cdot 37^{2} + 19\cdot 37^{3} + 26\cdot 37^{4} +O\left(37^{ 5 }\right)$
$r_{ 6 }$ $=$ $ 5 a + 36 + \left(12 a + 16\right)\cdot 37 + \left(36 a + 30\right)\cdot 37^{2} + \left(13 a + 20\right)\cdot 37^{3} + \left(23 a + 29\right)\cdot 37^{4} +O\left(37^{ 5 }\right)$
