%N Number of elements added at n-th stage to the toothpick structure of A327330.
%C The word of this cellular automaton is "ab".
%C The structure of the irregular triangle is as shown below:
%C a,b;
%C a,b;
%C a,b,a,b;
%C a,b,a,b,a,b,a,b;
%C a,b,a,b,a,b,a,b,a,b,a,b,a,b,a,b;
%C ...
%C Row lengths are the terms of A011782 multiplied by 2, also the column 2 of A296612.
%C Columns "a" contain numbers of I-toothpicks.
%C Columns "b" contain numbers of V-toothpicks.
%C For further information about the word of cellular automata see A296612.
