If you are looking for exponential output volumes then run a market
basket test. You will need only a few thousand baskets with 100 items
or so. Set min support very low (5%) and confidence at 80% and you
should get a flood of data. Any FIS algorythm should do the job.

For my benchmark purpose, I am looking for some non-trivial, real life
applications which creates *bigger* output than its input. Trivial
example I
can think about is cross join...
I really appreciate if you share your knowledge with me.
