%N Ranks of (even i)+(odd j)*r when all i+j*r are ranked, r=golden ratio, i>=0, j>=0.

%e Writing (i,j) for i+r*j, the first 7 in the ranking are

%e (0,0), (1,0), (0,1), (2,0), (1,1), (3,0), (0,2);

%e the rank where i is even and j is odd is a(1)=3.

%Y Cf. A183987, A183988, A183989, A183990, A183992, A183993.
