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 Sequence and first differences include all square numbers exactly once.
%C This sequence diverges from A000330 as 4900 (which is 70^2) appears in the sequence itself - thus won't be added to any a(n).
%e Superpose sequence and first differences:
%e 1 5 14 30 55 91 140 204 285 385 506 650 819 1015
%e .4.9..16..25..36..49...64...81...100...121...144...169...196
%e All square numbers appear once and only once, either in the sequence itself or in the first differences.
