 OFFSET 1,2 COMMENTS The word of this cellular automaton is "ab". The structure of the irregular triangle is as shown below: a,b; a,b; a,b,a,b; a,b,a,b,a,b,a,b; a,b,a,b,a,b,a,b,a,b,a,b,a,b,a,b; ... Row lengths are the terms of A011782 multiplied by 2, also the column 2 of A296612. Columns "a" contain numbers of V-toothpicks. Columns "b" contain numbers of I-toothpicks. See the example. For further information about the word of cellular automata see A296612. LINKS EXAMPLE Triangle begins: 1,2; 4,4; 4,6,12,8; 4,6,12,12,10,16,32,16; 4,6,12,12,10,16,32,20,12,18,36,36,26,42,84,32; 4,6,12,12,10,16,32,20,12,18,36,36,26,42,84,40,16,24,48,44,24,40,80,48,32,48,... It appears that right border gives the even powers of 2. CROSSREFS First differences of A327332. Column 1 gives A123932. Cf.
