Clearly, you are not counting 0 = sum({}) as one of these sums. Personally, I would include it.
This wouldn't change this sequence, but it would change A119347 and A119348. A quick check shows that this "incremented" version of A119347 is not in the database.

...
Values of n such that the number of distinct sums of
distinct divisors of n is less than 2^tau(n) - 1 (clearly,
the latter is the largest number of possible distinct sums).
...
The number of distinct sums of distinct divisors of n are
given in A119347 and the triangle of the actual sums are
given in A119348 (both already submitted).
Thanks for just reading this.
