Some more exact enumeration results for 1D cellular automata
Peter Grassberger · Journal of Physics A Mathematical and General · 1987
The author presents exact enumeration results for the elementary cellular automation rules 22, 30, 45 and 120 in Wolfram's notation. Obtained by a new algorithm, they improve previous results considerably. They confirm the existence of 'hidden' power-behaved long-range correlations in the patterns created by these rules.
