So 7 riffles can produce every permutation equiprobably, right?
Is there a smaller number of riffles that can produce every permutation, not necessarily equiprobably?

I thought you made up that word, but you didn't! Thanks for teaching me somethign new!

Heuristically, there are a finite number of outputs of a riffle shuffle (probably fairly large; basically the number of different ways that you can clump cards together, 52^20 or thereabouts). But any finite number of outputs raised to the 7th power is not going to divide 52 factorial, in terms of the number of output possibilities.
