%N Number of partitions into distinct parts, with some sub-partitions having equal sums. Partition(n) = [a, b, c...] where 2n = 2^a + 2^b + 2^c + ...
%C Partition encoding as in A029931. Complement of A059519.
%e 13=1+4+8 so Partition(13) = [1,3,4], whose sub-sums are 0,1,3,4,5,7 and 13, with 4 twice (once from 1+3 and once from 4 by itself).
%Y A029931, A059519.
