Defining polynomial

 $f(x)$ $=$ $$x^{7} - x^{6} + 2x^{5} - 2x^{4} + 2x^{3} - 2x^{2} + 2x - 1$$ x^7 - x^6 + 2*x^5 - 2*x^4 + 2*x^3 - 2*x^2 + 2*x - 1 .

The roots of $f$ are computed in an extension of $\Q_{ 277 }$ to precision 5.

Minimal polynomial of a generator $a$ of $K$ over $\mathbb{Q}_{ 277 }$: $$x^{2} + 274x + 5$$
