Ace sequencing

Is it feasible to sequence an 8-deck triple R&R?

If the answer is yes then what is the optimum number of key cards?

I am aware that the more decks you have, the more qualifiers you need.

I would have thought triple keying is out of the question � the minimum intact sequence required would be 25 cards. Even two keys are a stretch, is single keying worthwhile?
