Roots of defining polynomial
The roots of $f$ are computed in an extension of $\Q_{ 313 }$ to precision 5.
Minimal polynomial of a generator $a$ of $K$ over $\mathbb{Q}_{ 313 }$:
\( x^{2} + 310x + 10 \)
Roots:
$r_{ 1 }$ | $=$ | \( 119 + 78\cdot 313 + 158\cdot 313^{2} + 256\cdot 313^{3} + 278\cdot 313^{4} +O(313^{5})\) |
$r_{ 2 }$ | $=$ | \( 68 a + 262 + \left(148 a + 309\right)\cdot 313 + \left(207 a + 252\right)\cdot 313^{2} + \left(199 a + 152\right)\cdot 313^{3} + \left(240 a + 83\right)\cdot 313^{4} +O(313^{5})\) |
$r_{ 3 }$ | $=$ | \( 219 + 150\cdot 313 + 203\cdot 313^{2} + 244\cdot 313^{3} + 119\cdot 313^{4} +O(313^{5})\) |
$r_{ 4 }$ | $=$ | \( 51 a + 281 + \left(203 a + 81\right)\cdot 313 + \left(66 a + 308\right)\cdot 313^{2} + \left(145 a + 67\right)\cdot 313^{3} + \left(177 a + 84\right)\cdot 313^{4} +O(313^{5})\) |
$r_{ 5 }$ | $=$ | \( 245 a + 153 + \left(164 a + 60\right)\cdot 313 + \left(105 a + 101\right)\cdot 313^{2} + \left(113 a + 231\right)\cdot 313^{3} + \left(72 a + 292\right)\cdot 313^{4} +O(313^{5})\) |
$r_{ 6 }$ | $=$ | \( 97 + 243\cdot 313 + 235\cdot 313^{2} + 174\cdot 313^{3} + 234\cdot 313^{4} +O(313^{5})\) |
