%N Total number of OFF (white) cells after n iterations of the "Rule 135" elementary cellular automaton starting with a single ON (black) cell.

%C This is (apart from an index shift) the same as A110267. The reason is that Rule 135 is obtained from Rule 30 by inverting both colors of the 4 cells correlated by the rules. - _R. J. Mathar_, Dec 16 2015
