Equivalently, G misses out a dump with a smallest amount of petrol among all possible misses that give a safe result. It is clear that a greedy step is possible if any step is, so we have only the second condition to check. -. ,jk] is a safe solution, then there is another safe solution incorporating i that is of no greater length. If i = jp for some p, then there is nothing to prove. ,J~] greater than i, otherwise.

Note that while the definitions of 'balanced' and 'universal' call upon each other recursively, there is no bad circularity. Using these definitions, it is easy to define a weak n-category. While the definition below does not explicitly depend on n, it depends on n through the definition of 'universal' niche-occupant.
