- for each for some .
- A function is said to be bijective (or a bijection or a one-to-one correspondence) if it is both injective and surjective.

- The Garden of Eden Theorem (Theorem 5.3.1) implies that every surjective cellular automaton with finite alphabet over an amenable group is necessarily pre-injective. In this section, we give an example of a surjective but not pre-injective cellular automaton with finite alphabet over the free group .
