Aren't the partitions of 6 in Mathematica order
6,
5, 1,
4, 2,
4, 1, 1
which leads to a 1, 2, 2, 2 in the sequence A115623 (I see a 1,2,2,1 there)

while the partitions of 6 in Abramowitz-Stegun order are
6,
1, 5,
2, 4,
3, 3
which leads to a 1,2,2,1 in the sequence A103921?

In other words, I think maybe there's a mistake in A115623 that leads
to the apparent duplication.  Franklin?  You're the expert on these,
if I remember correctly from some seqfan exchanges some time ago.

I'll echo the 99% sureness and also note the bad line break in the URL above.
