The OEIS Foundation is supported by donations from users of the OEIS and by a grant from the Simons Foundation.

Year-end appeal: Please make a donation to the OEIS Foundation to support ongoing development and maintenance of the OEIS. We are now in our 56th year, we are closing in on 350,000 sequences, and we’ve crossed 9,700 citations (which often say “discovered thanks to the OEIS”).

 OFFSET 1,2 COMMENTS The "word" of this cellular automaton is abcb. The associated sound to the animation of this cellular automaton could be [tick, tock, tack, tock], [tick, tock, tack, tock], and so on. For more information about the "word" of a cellular automaton see A296612. LINKS N. J. A. Sloane, Catalog of Toothpick and Cellular Automata Sequences in the OEIS EXAMPLE The structure of this irregular triangle is shown below:    a,  b,  c,  b;    a,  b,  c,  b;    a,  b,  c,  b,  a,  b,  c,  b;    a,  b,  c,  b,  a,  b,  c,  b,  a,  b,  c,  b,  a,  b,  c,  b; ... So, written as an irregular triangle in which the row lengths are the terms of A011782 multiplied by 4, the sequence begins:    1,  2,  4,  6;    8,  6, 12, 10;    8, 12, 18, 24, 24, 20, 30, 18;    8, 12, 18, 24, 28, 28, 46, 38, 48, 46, 68, 66, 68, 50, 72, 36;   10, 12, 18, 24, 28, 28, 46, 42, 52, 60, 80, 88,92, 90, 118, 84, 74, ...
