If I remember correctly from my childhood years, this lottery is with no repetition.


What I do not remember, is if the order is important or not.



If the order is important, then the number under the question is

    42*41*40*39*38*37.



If the order is not important, then the number is the number of combinations

    %2842%2A41%2A40%2A39%2A38%2A37%29%2F%281%2A2%2A3%2A4%2A5%2A6%29.

Solved.
