Summary edit
| Description |
English: A fundamental domain of the maximal order of the field K obtained by adjoining to Q a root of f(x) = x3 − x2 − 2x + 1. This field is a Galois extension of degree 3. Its discriminant is 49=72. Accordingly, the volume of the fundamental domain is 7. A basis for its lattice is (approximately) {(1,1,1),(−1.2469796037,0.4450418679,1.8019377358),(1.8019377358,−1.2469796037,0.4450418679)}. Computed using PARI/GP. Plotted using Mathematica. |
