## Defining polynomial

 $f(x)$ $=$ $$x^{6} - 3 x^{4} + 9 x^{2} - 18 x + 12$$  .

The roots of $f$ are computed in an extension of $\Q_{ 7 }$ to precision 8.

Minimal polynomial of a generator $a$ of $K$ over $\mathbb{Q}_{ 7 }$: $$x^{2} + 6 x + 3$$

Roots:
 $r_{ 1 }$ $=$ $$3 + 2\cdot 7 + 6\cdot 7^{2} + 6\cdot 7^{3} + 6\cdot 7^{4} + 6\cdot 7^{5} + 6\cdot 7^{6} + 7^{7} +O(7^{8})$$ $r_{ 2 }$ $=$ $$2 + 5\cdot 7 + 4\cdot 7^{2} + 6\cdot 7^{3} + 2\cdot 7^{4} + 3\cdot 7^{5} + 7^{6} + 4\cdot 7^{7} +O(7^{8})$$ $r_{ 3 }$ $=$ $$2 a + 1 + 3\cdot 7 + \left(2 a + 6\right)\cdot 7^{2} + \left(5 a + 1\right)\cdot 7^{4} + \left(5 a + 3\right)\cdot 7^{5} + \left(3 a + 4\right)\cdot 7^{6} +O(7^{8})$$ $r_{ 4 }$ $=$ $$6 a + 3 + \left(a + 6\right)\cdot 7 + \left(5 a + 2\right)\cdot 7^{2} + \left(2 a + 1\right)\cdot 7^{3} + \left(a + 6\right)\cdot 7^{4} + 5\cdot 7^{5} + \left(a + 5\right)\cdot 7^{6} + \left(6 a + 5\right)\cdot 7^{7} +O(7^{8})$$ $r_{ 5 }$ $=$ $$5 a + 3 + \left(6 a + 1\right)\cdot 7 + \left(4 a + 1\right)\cdot 7^{2} + \left(6 a + 6\right)\cdot 7^{3} + \left(a + 5\right)\cdot 7^{4} + \left(a + 3\right)\cdot 7^{5} + \left(3 a + 2\right)\cdot 7^{6} + \left(6 a + 4\right)\cdot 7^{7} +O(7^{8})$$ $r_{ 6 }$ $=$ $$a + 2 + \left(5 a + 2\right)\cdot 7 + \left(a + 6\right)\cdot 7^{2} + \left(4 a + 5\right)\cdot 7^{3} + \left(5 a + 4\right)\cdot 7^{4} + \left(6 a + 4\right)\cdot 7^{5} + \left(5 a + 6\right)\cdot 7^{6} + 3\cdot 7^{7} +O(7^{8})$$
