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 Joint-rank array of numbers j*r^(i-1), where r=1+sqrt(3), read by antidiagonals.
%C Joint-rank arrays are defined in the first comment at A182801. Every positive integer occurs exactly once, so that as a sequence A182832 is a permutation of the positive integers.
%F T(i,j)=SUM{floor(j*(1+sqrt(3))^(i-n)): n>=1}.
