JIM nominates me:
​
quote:
The actual number of times you have to shuffle a deck, in order to get absolute randomness is 7 times!
​
That depends on how you shuffle it. Perfect riffle shuffles, alas, impose a secondary order upon the deck. If you know how the deck started off and you execute perfect riffle shuffles, you will know the exact order of the deck.
​
If I recall correctly, if you execute 8 perfect riffle shuffles, you restore the original order of the deck.
​
And thanks.
