Year-end appeal: Please make a donation to the OEIS Foundation to support ongoing development and maintenance of the OEIS. We are now in our 61st year, we have over 378,000 sequences, and we’ve reached 11,000 citations (which often say “discovered thanks to the OEIS”).

%N Ranks of (even i)+j/r, when all i+j/r are ranked; r=golden ratio (1+sqrt(5))/2, i>=0, j>=0. Complement of A184332.

%e Writing (i,j) for i+j/r, the first 7 in the ranking are (0,0), (0,1), (1,0), (0,2), (1,1), (0,3), (2,0); the ranks where i is odd are 3,5 and the ranks where it is even are 1,2,4,6,7.
