Galois action

Roots of defining polynomial

The roots of $f$ are computed in an extension of $\Q_{ 7 }$ to precision 6.
Minimal polynomial of a generator $a$ of $K$ over $\mathbb{Q}_{ 7 }$: \( x^{2} + 6x + 3 \) Copy content Toggle raw display
Roots:
$r_{ 1 }$ $=$ \( 2 + 6\cdot 7 + 5\cdot 7^{2} + 5\cdot 7^{3} + 7^{4} + 3\cdot 7^{5} +O(7^{6})\) Copy content Toggle raw display
$r_{ 2 }$ $=$ \( 6 + 5\cdot 7 + 5\cdot 7^{2} + 6\cdot 7^{4} + 3\cdot 7^{5} +O(7^{6})\) Copy content Toggle raw display
$r_{ 3 }$ $=$ \( 4 a + \left(4 a + 5\right)\cdot 7 + 4 a\cdot 7^{2} + \left(2 a + 3\right)\cdot 7^{3} + 6 a\cdot 7^{4} + \left(a + 3\right)\cdot 7^{5} +O(7^{6})\) Copy content Toggle raw display
