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”).

EXAMPLE
a(5)=171 because the sum of last five *digits* of the sequence beginning with 0,0,0,0,4, (four zeros followed by a 4) enters in a loop whose length is 171 terms; so a(5)=171
a(6)=39 because "Sum of last six digits" beginning with 0,0,0,0,0,4 enters in a cycle of 39 terms.
