Hans,  Wow!  Congratulations!

I am adding the following line to both A228474 and A248939:

_Hans Havermann_, running code from _Hugo van der Sanden_, has found that
row 11281 has length 3285983871526. - _N. J. A. Sloane_, Mar 22 2019

 - is that OK?  Except it can't be quite right, I think, because A228474
has this comment:

a(n) + 1 = length of row n in tables A248939 <https://oeis.org/A248939> and
A248973 <https://oeis.org/A248973>. - Reinhard Zumkeller
<https://oeis.org/wiki/User:Reinhard_Zumkeller>, Oct 20 2014

So the comments that I'm adding to the two sequences should have numbers
that differ by 1.  Hans, which sequence gets 3285983871526, and which
sequence gets 1 more or less?
