Can you elaborate the technicalities involved !! What I did is first I made pairs (5,5,5,5) or (4,6,4,6) … now how to proceed further , got confused

just watch for the combinations and their possible arrangement like 6,6,6,2/6,2,6,6/6,6,2,6/2,6,6,6 etc

This is not a question that can be asked in exams ,if they want to test your concept they will restrict the max dices to 3.
