COMMENTS
The word of this cellular automaton is "abc", the same as the word of A296511, but here the irregular triangle starts with three rows of length 3 as shown below:
a,b,c;
a,b,c;
a,b,c;
a,b,c,a,b,c;
a,b,c,a,b,c,a,b,c,a,b,c;
a,b,c,a,b,c,a,b,c,a,b,c,a,b,c,a,b,c,a,b,c,a,b,c;
...
Row lengths are 3, 3, 3, 6, 12, 24, 48, 96, ... or in other words: 3 together with the column 3 of A296612.
