Yeah. What I'll do is run a program to populate a EUPHORIA database with
every possible combination... or a significant portion thereof (for test
purposes) and measure the performance...

Yes, it's for the lottery. I need a program that will spew extra sets as
needed. We maintain a database of the picks we use in our club*, and every
so often, when we hit 4-of-6 or something, we'll need a couple hundred or
more picks. I want to generate these picks on the fly but not duplicate any
in the database.
I guess I'm just curious as to how far EUPHORIA can handle this kind of
number crunching, especially when the picks get up into the thousands or
millions or whatever. It's more an exercise than anything applicable (at
least for now).
So, you see, I can't have duplicates.
