WebbIf we have a regular polyhedron, the reflection of triangle CAD in the plane of ABC will be an adjacent face of the same polyhedron, and the angle between the two faces will be 2δ. To find γ, note that we can compute the length EC in two ways: either as s sin ½α from triangle AEC, or as s cos γ sin ½β from triangle BEC.

WebbIt is well known that there are exactly five convex regular polyhedra in dimension 3, the Platonic solids. In dimension 4, there are exactly six convex regular polytopes. In dimensions n > 5, there are exactly three regular polytopes: the hypercube, regular simplex, and cross polytope (see, e.g., [3, p. 1361). After introducing and exploring the WebbAs the simplex method goes through the edges of this polyhedron it is generally true that the speed of convergence of the algorithm is not smooth.

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. birth of a tragedy
