WebbAbstract : Besides simplices, n-cubes form an important class of simple polyhedra. Unlike hyperbolic Coxeter simplices, hyperbolic Coxeter n-cubes are not classified. In this work, we first show that there are no Coxeter n-cubes in Hn for n≥10. Then, we show that the ideal ones exist only for n=2 and 3, and provide a classification.

We transform the inequalities into equations with the addition of variables. For this, we introduce a slack variable (x 3, x 4, x 5) in each of the constraints of the form ≤, to transform them into equalities (see lesson on the standard form): 2 x 1 + x 2 + x 3 = 18. 2 x 1 + 3 x 2 + x 4 = 42.
