comment Looking for a bijection between this set and natural numbers
I had some time to read this through, and it was very helpful. The bijection between $A_{k, M}$ and that subset is just impressive. At the moment, I am still unable to truly understand it but I'll think harder. However, I used another method for mapping the combination to an integer, the "combinatorial number system" as described by D. Knuth. For the time being, I am satisfied with this result.

Well, you aren't allowed! Sorry for not being explicit enough. They have to be integers.

I do mean a closed interval.

I have searched for information about them and I don't feel like I am able to apply them to this scenario right away. If you write an answer, I'd be glad to read it.

comment Function mapping combinations to natural numbers
Thank you. Thanks to your suggestions I've managed to write a small Java library to deal with combinations.
