Examples
The finite sequence can be written as an array of four columns as shown below: 1, 4, 8, 8; 12, 20, 16, 8; 24, 16. The first column gives the number of toothpicks of length 2. The second column gives the number of D-toothpicks. 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.
