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”).

Numbers k such that A003557(k) divides A276086(k), where A003557(k) is k divided by its largest squarefree divisor, and A276086 is the primorial base exp-function.
