7. Conclusion

We have seen that many functions are clocking-computable, namely, the even bijective ones and the non-bijective ones with enough "loss" in their image.

The elementary cellular automaton ECA-57 can be used to implement an etherealware computing device: The computed function is a result only of the clocking order.

Temporal order of activating the CA cells is thus a new way to encode algorithms, a "volatilization of information".

We increased the size for example programs from n ¼ 3 in [10, 14] to n ¼ 4 and are confident to also be able to tackle the case n ¼ 5.

From n ¼ 6 onwards, we shall need more mathematical concepts, e.g., from group theory.
