Comments

The "word" of this cellular automaton is abcbc.

The associated sound to the animation of this cellular automaton could be [tick, tock, tack, tock, tack], [tick, tock, tack, tock, tack], 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,  c;
   a,  b,  c,  b,  c;
   a,  b,  c,  b,  c,  a,  b,  c,  b,  c;
   a,  b,  c,  b,  c,  a,  b,  c,  b,  c,  a,  b,  c,  b,  c,   a,  b,  c,  b,  c;
...
So, written as an irregular triangle in which the row lengths are the terms of A011782 multiplied by 5, the sequence begins:
   1,  2,  4,  6,  8;
   6,  6, 10, 16, 20;
  12, 10, 16, 20, 32, 24, 22, 34, 36, 40;
  16, 14, 20, 24, 40, 32, 32, 44, 48, 64, 48, 42, 58, 70, 104, 74, 60, 78, 78, 80;
  24, 14, 20, 24, 40, 36, 40, 50, 52, 72, ...
