%N 1 if there is a winning strategy for misère Sprouts with n initial points, else 0.
%C This comes from changing "W" to "1" and "L" to "0" in Figure 1, p. 2 of Lemoine & Viennot's paper.
%C Lemoine & Viennot conjecture that, for n > 4, a(n) = 1 if and only if n is 0, 4, or 5 mod 6. - _Charles R Greathouse IV_, Dec 13 2012
