3030 Jaccia has the property that, when started from this condition (entire
3131 maze filled with slime cells), the automaton will eventually reach a
32 fixed point (steady state) which contains all possible paths from food
33 to food.
32 fixed point (steady state) which contains all possible orthogonal paths
33 from food to food. (Orthogonal paths means, a diagonal isn't considered
34 a path.)

3536 Jacciata is similar, but has the property that when it reaches a fixed
3637 point, it will contain the *shortest* path from food to food, if such a
3738 path exists and is unique. If no such path exists, or is not unique, the
3839 result is undefined. It is otherwise similar to Jaccia.

40 The behaviour of both automata is also undefined if the slime
41 configurations are not orthogonal (that is, if there are any diagonal
42 slime paths.)

75 to be written more succinctly.
