Seqfans,

Sum of entries in the n-th row of triangle A140993 (http://oeis.org/A140993)
seems to equal 2^n, with anti-diagonal sums of the triangle being a
sequence beginning as

{1,1,2,3,4,7,9,15,20,32,44,...}

which is evidently not in OEIS.

Does the n-th row of A140993 tend to A141682 (http://oeis.org/A141682), as
n --> infinity?

Regards,

Ed Jeffery
