%F See A065775.
%F Empirical g.f.: x*(2*x^122*x^11+2*x^104*x^9+2*x^8x^7x^64*x^44*x^2x3) / ((x1)^3*(x^2+1)*(x^2+x+1)^2).  _Colin Barker_, May 04 2014
%e a(3)=5=3+1+1, these summands being the least numbers of knight's moves from (0,0) to the points (3,0), (2,1), (1,2) on the 3rd diagonal in the 1st quadrant  which is 1/4 of a 3rd concentric square about the origin. See A183052 for sums over the concentric squares.
%Y Cf. A065775, A183049, A183051.
