%e The finite sequence can be written as an array of four columns as shown below:

%e 1, 4, 8, 8;

%e 12, 20, 16, 8;

%e 24, 16.

%e The first column gives the number of toothpicks of length 2.

%e The second column gives the number of D-toothpicks.

%e The third column gives the number of toothpicks of length 1.

%e The fourth column gives the number of T-toothpicks.

%e The sequence contains exactly 10 terms.

%Y Cf. A294962.

%Y Cf. A139251 (toothpicks), A160173 (T-toothpicks), A194701 (D-toothpicks), A220501.
