What is the Fixed-Number Lotto Combination Generator?

This generator lets you first pick 12 or 20 fixed numbers, then produces all possible combinations of 6 from them. Picking 12 yields 924 combinations and picking 20 yields 38,760 combinations, and you can narrow down to the desired count using filters such as high AC priority, balanced odd/even ratio, and minimized consecutive numbers. It is useful when you trust certain numbers but are unsure which combination is best, or want to build combinations within a specific number range.

What is AC (Arithmetic Complexity)?

AC (Arithmetic Complexity) is an indicator of the diversity of a lotto number combination. It measures the number of unique differences by calculating the difference of each number pair. Example: [1, 2, 3, 4, 5, 6] → differences 1,2,3,4,5 → AC=5 / [1, 11, 21, 31, 41, 45] → differences 4,10,14,20,24,30,40,44 etc → AC=13. Generally, a higher AC value means numbers are spread more evenly, while a lower AC value means numbers are more consecutive or regular.
