Denomination sequence. Start with the 0th and first coins of value 1 cent: a(0)=a(1)=1. Thereafter a(n), the value of the n-th coin (n>=2), is the number of ways to make change for n cents in earlier coins. The two one-cent coins are considered distinct.
1, 1, 3, 5, 7, 10, 14, 19, 25, 32, 42, 53, 66, 82, 101, 124, 150, 181, 216, 257, 306, 361
