This calculator generates all possible combinations of items from different sets/lists. Commas should separate the values of your sets. I hope the default values in the table below give a clear understanding of how you should use the calculator.
The generator itself is straightforward - its logic is the same as the logic for any positional numbering system. Each set represents the position, and each set value represents a digit. If we had three sets, each of them consisting of digits from 0 to 9, all we need to do is to count from 000 to 999.
