%N A100529 a(n) = minimal k such that n has a partition into k parts with the property 
               that every number <= m can be partitioned into a subset of these 
               parts.
%D A100529 E. O'Shea, M-partitions: optimal partitions of weight for one scale pan, 
               Discrete Math 289 (2004), 81-93.

               694-698.
%F A100529 If 2^m + 2^(m-1) - 1 <= n <= 2^(m+1) - 1 for some m, let i = 2^(m+1) 
               - 1 - n. Then a(n) = A000123([i/2]). This determines half the values.
