Hi Tami,
When you say learners can enter the set of codes you specified regardless of the order, do you mean as long as the correct numbers? are present, they should be considered correct? So for the set a, b, c, d, e, and f, they can enter (b, d, e, a, f, c) or (f, e, d, c, b, a), etc. Is that right?
That might be possible with a fill-in-the-blank quiz, but you will have to enter each possible permutation for the sets that can be entered regardless of order.
I understand all the different combinations may be daunting to enter in the Acceptable response. We can wait for others in the community to make their suggestions on how you can come up with this quiz.
