The OEIS Foundation is supported by donations from users of the OEIS and by a grant from the Simons Foundation.

 Please make a donation to keep the OEIS running. We are now in our 56th year. In the past year we added 10000 new sequences and reached almost 9000 citations (which often say "discovered thanks to the OEIS"). Other ways to donate

 OFFSET 2,3 COMMENTS It is assumed that each of the two darts scores. LINKS Wikipedia, Darts EXAMPLE a(2) = 1 because the only possible throw is (1,1). a(7) = 3 because possible throws are (1,6), (2,5) and (3,4). a(103) = 0 because it is not possible to get a score of 103.
