And by the way, this is a good reason to select a natural "up to" -limit for
the
terms in b-file, if there are any such natural limits for the sequence in
question.
In this case, 1596 = A026905(18). (A026905 = Partial sums of A000041,
partition numbers.)
E.g., for any binary related sequences I use powers of 2, or powers of 2 - 1
if the starting offset is 0.
