Nicolay Avilov: Robert, I didn't think it was important, but now I will. I am preparing a problem with this sequence for publication on the Russian-language website https://elementy.ru/problems/a/5276093/Nikolay_Avilov,
where 46 of my problems have already been published.
Typically, in the afterword to a problem, I inform readers that the sequence has been published in the OEIS. I will do the same with this sequence if you take it into the database.

Robert Munafo: The existence of A319006 alone does not give us license to generate minor variants, without actual research, related work on web pages, etc. to boost a likelihood that anyone would ever try to look up the variant.
