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”).

COMMENTS

A045759 generalizes to k consecutive integers that all have the same value of f(n), where f(n) = sum of digits of n plus sum of digits in prime factors of n. The sequence shows the integer which starts the smallest set of k (and no more than k) consecutive integers having this property.
