Four color theorem: Infinite switches are not enough :-( :-(

really_bad_case-ariadne_step-5-12-7-32-6-15-10A new edge 12-7 that connects the edges 6-10 and 32-15.

With this case seems that infinite random switches throughout the entire graph do not solve the impasse, which is really really really bad.
