COMMENTS

A number n is in this sequence iff n appears anywhere in the terms of A_n, not just in the terms that are visible in the entry.

Is 53873 in this sequence? (A rhetorical question!) - Tanya Khovanova, Aug 09 2007

Is 53169 in this sequence? (A rhetorical question!). - Raymond Wang, Oct 07 2008

I skipped 241 since it appears that A000241(14) > 241, but as the 13th and further terms are not known this is not certain. The next term in the sequence is almost surely 319, but finding the least k for which A000319(k) = 319 requires calculating a chaotic sequence to high precision. - Charles R Greathouse IV, Jul 20 2007
