(Greetings from The On-Line Encyclopedia of Integer Sequences!)
A299771 a(n) is the number of elements added at n-th stage in the structure of the finite cellular automaton of A299770. 1
1, 4, 8, 8, 12, 16, 16, 8, 24, 8 (list; graph; refs; listen; history; text; internal format)



The word of this cellular automaton is abcd. For more information see A296612.

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.


Very similar to A294963.
