 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 59th year, we have over 358,000 sequences, and we’ve crossed 10,300 citations (which often say “discovered thanks to the OEIS”). Other ways to Give

 A210023 a(0)=1. Let S = string of digits of a(0),a(1),a(2),... To get a(n+1) (n>=0), subtract next element of S from a(n) if that would give a positive number different from a(0),...,a(n), otherwise add it to a(n). 3
