Numerical computation of orbits

The following pictures show the reduced phase space of billiard map, where the dihedral symmetry has been factored out. The horizontal tex2html_wrap_inline583 -axes gives the place of impact from 0 to tex2html_wrap_inline587 and the vertical tex2html_wrap_inline589 axes parameterizes the angle of impact. For each of the 14 parameter values we see 13 x 11 orbits each with 100 iterations.
