\item P.M.B. Vit\'anyi, On a problem in the collective behavior of automata, \it Discrete Mathematics {\bf 14} \rm (1976), 99 - 101. Abstract: Varshavsky defines the function L(n) as the maximum finite length of a configuration which can be grown from one activated automaton in a linear space of identical finite=state automata having n internal states. It is shown that L increases faster than any computable function, even if the flow of information in the linear cell space is restricted to one direction.
