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.

Examples

			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, ...
