And without communicating among themselves, how does that even help?
the only way I see right now is if everyone in the group realizes that in summing 4 numbers between 1 and 6 the most common sum is 14 if everyone guesses off that then:

z+x+y=14-a assume player one guesses 5
9-(x+y)=z so player two knowing the two in front of him can safely say his number is such and such based on the knowledge about 14 and player 1's guess. though I guess this is still a probabilistic way at best.

so since it's asking for a function I'm guessing f(a,x,y) means 14-(a,x,y)=z is my best guess but I'm stupid. and I still don't even understand the answer format other than involving w^3 digits for 1-w.
