For A001399, the generating function is definitely correct.

Subject: [seqfan] Three bfile discrepancies

Georg Fischer has been running some of my Java programs against existing
bfiles and finding a fair number of discrepancies.  Many of these have now
been fixed one way or the other.

The following three cases are ones where we are not confident as to which
is wrong.  In two of the cases at least one other program in the entry also
disagrees with the bfile value -- but by itself that might not be enough
because programs can be related or based on faulty formulas.

So this is plea for someone else to try and compute these values.  None of
them are hard in the sense that it should only take seconds to reach the
problematic value.

A000025(117) b-file: 43799, computed: 48780
A001399(14001) b-file: 16340334, computed: 16342668
A001662(29) b-file: 458566039538034187375774891, computed:
113265811765894444281816398077
