@Eddy: What is  φ ? Is is somehow related to Euler's  φ function?

anonymous · Answer

I think it is 0
because $$\phi = 0$$ in the set theory but I maybe mistaken ofc..

directrix · Answer

The Euler's phi function (that I remember) of a positive  integer x has to do with the number of positive integers not greater than x  and relatively prime to x.

anonymous · Answer

So what should be the answer according?

directrix · Answer

I don't know that the phi function has anything to do with Eddy's problem. I saw the φ2 and thought about Euler's Phi function.Eddy needs to tell us what φ2  means in the context of his question.

anonymous · Answer

Hmm true, it is applicable both ways, might even be something related to physics lol.
