COMMENTS
The word of this cellular automaton is abcd. For more information see A296612.
EXAMPLE
The finite sequence can be written as an array of four columns as shown below:
1, 4, 8, 8;
12, 16, 16, 8;
24, 8.
The first column gives the number of toothpicks of length 2.
The second column gives the number of D-toothpicks of length sqrt(2).
The third column gives the number of toothpicks of length 1.
The fourth column gives the number of T-toothpicks.
The sequence contains exactly 10 terms.
CROSSREFS
