Clark Kimberling: Regarding Joerg's  Comment, I may be missing something.  The example at A240181 indicates that A240450(6) = 4, not 3.

COMMENTS

To match the definition, all terms need to be decreased by 1 (because the rows in A240181 start with k=0). So this appears to be an incorrect duplicate of A067731. - Joerg Arndt, Jul 30 2017
