Dear Seq Fans,
I just came across an old paper
of John Riordan's, which ostensibly deals with A046919 and A000571.
His goal is to find a formula for A000571.
But I think he made a mistake.
His formula does not give A000571, but what turns out to be a new sequence,
A210726.
His computation of A046919 seems OK, though, except that when I extended
his numbers a zillion years ago, I made a mistake.
I have just corrected A046919 and added a b-file for it.
This leaves A000571. There is a reasonable-looking formula.
Can someone produce a b-file?
