 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 60th year, we have over 367,000 sequences, and we’ve reached 11,000 citations (which often say “discovered thanks to the OEIS”). Other ways to Give

 OFFSET 1,2 COMMENTS Similar in definition to A033036. As n increases, it is most likely that A212495(n) < A033036(n), although exceptions to this rule can be found. I conjecture that A212495(n) > A033036(n) for only finitely many values of n. LINKS Table of n, a(n) for n=1..59. EXAMPLE 30 is represented by "28" in base 11. Both digits in this representation are even, thus 30 belongs to the sequence.
