Hmmm! A112531 is indeed mysterious.

In case it will help, the following are the contributions
from Alford Arnold in 2005. Maybe there are clues in the entries dated
September 2005.

%C A036035 A closely related sequence, A096443(n), gives the number of
partitions of the n-th multiset. - _Alford Arnold_, Sep 29 2005
%F A045531 a(n) = A047969(n,n). - _Alford Arnold_, May 07 2005
%C A047969 a(n-1, k-1) is the number of ordered k-tuples of positive
integers such that the largest of these integers is n. - _Alford Arnold_,
Sep 07 2005
%C A086602 The sequence 2 12 39 95 195 ... can be decomposed as 1 5 14 30
55 ... A000330 plus 1 7 25 65 140 ... A001296. - _Alford Arnold_, Jun 29
2005
%A A089574 _Alford Arnold_, Dec 29 2003; extended May 04 2005
%C A093936 Note that A093936 can be readily extended by combining
appropriate values from A096443. Row sums of A093936 yield A035310 and
embeded sequences include A000041, A035098 and A000110. - _Alford Arnold_,

%E A093936 More terms from _Alford Arnold_, Nov 19 2005
%A A095705 _Alford Arnold_, Jul 04 2004, Nov 22 2005
%C A096443 A000041 and A000110 are subsequences for conjugate partitions.
A000070 and A035098 are also subsequences for conjugate partitions. -
