%N The number of ways that a score of n can be obtained using three darts on a standard dartboard.
%C It is assumed that each of the three darts scores.
%H Wikipedia, <a href="http://en.wikipedia.org/wiki/Darts">Darts</a>
%e a(3) = 1 because the only possible throw is (1,1,1).
%e a(6) = 3 because possible throws are (1,1,4), (1,2,3) and (2,2,2).
%e a(163) = 0 because it is not possible to get a score of 163.
%Y Cf. A241746, A242681, A242717, A242718.
