they are clearly not the same:
A051038 11-smooth numbers: i.e. numbers whose prime divisors are
all <= 11.
..., 100, 105, 108, 110, 112, ...
A033637 Products of partition numbers A000041(n).
..., 100, 101, 105, 108, 110, 112, ...
A084347 Numbers which can be written as a*b*c*... where a, b, c are
numbers whose decimal expansions are repetitions of a single digit.
..., 100, 105, 108, 110, 111, 112,...
