Combinatorics. Permutation generator from N to M with repetitions

Good morning,

I am trying to generate all permutations of 3 Sets of ABC with permutation size of 17

I understand the outcomes are so many, 129,140,163 and the web page keeps crashing....if you can kindly do it from your end and send it to my email, I will really appreciate (mbaranikadenge@gmail.com), or if possible, you can also send the java code for that and i will run it in my IDE.

Your assistance will be highly appreciated
