Hi
when I choose 6 numbers (19, 21, 25, 32, 40 and 42) and set remove match 4 then I think that I filter out all combinations that include at least 4 selected number combinations.
After that I calculate package statistics and see that there is quads left behind:
19-21-25-32 (36 pc)
19-21-25-40 (39 pc)
19-21-25-42 (35 pc)
...
25-32-40-42 (0 pc)
can this problem be dealt?
