You draw three random cards and line them up on the table, creating a three-digit number, e.g., 425 or 837. In the weeks since I've posted the above reply, I've found that the NAME of the concept for what Ben is looking for is the "powerset" of the original set of 15 items. This will again give us a table containing all possible combinations. The same method is used here but for 1's here is a character and for 0's nothing.

Another issue is, if the input iterable is big, it is perhaps better to return a generator instead of everything in a list: Here is yet another solution (one-liner), involving using the itertools.combinations function, but here we use a double list comprehension (as opposed to a for loop or sum): You can also use the powerset function from the excellent more_itertools package.

Clicking the "Reset" button will restore the calculator to its default settings. It visits every element in turn, and either takes it or leaves it (we can directly see the 2^N cardinality from this algorithm). Next, we need to load the data as a connection only. The number of combinations is always smaller than the number of permutations. Repeat the steps above for each query. 3, 4] .
