Galois action

Roots of defining polynomial

The roots of $f$ are computed in an extension of $\Q_{ 71 }$ to precision 5.
Minimal polynomial of a generator $a$ of $K$ over $\mathbb{Q}_{ 71 }$: \( x^{2} + 69x + 7 \) Copy content Toggle raw display
Roots:
$r_{ 1 }$ $=$ \( 7 + 58\cdot 71 + 14\cdot 71^{2} + 19\cdot 71^{3} + 12\cdot 71^{4} +O(71^{5})\) Copy content Toggle raw display
$r_{ 2 }$ $=$ \( 12 a + 52 + \left(48 a + 4\right)\cdot 71 + \left(32 a + 13\right)\cdot 71^{2} + \left(48 a + 17\right)\cdot 71^{3} + \left(60 a + 68\right)\cdot 71^{4} +O(71^{5})\) Copy content Toggle raw display
