Q: A summation of the multiplication of reflected Mobius functions and their behavior for different values of $k$

UltradarkTake$$ \sum_{n=1}^{N} \mu(n)\mu(k-n)$$ where $\mu(n)$ is the Mobius function. I'd like the answers to include a plot of the function for $k=1,2,...,N$ all on the same plot to see how different they are. Why does a little change in $k$ create such a big change in the overall behavior of the fu...

Provide context :) At the moment your 'question' reads more like an order from someone, and not a request for help or information. Why is this of interest to you (and so, indirectly, why should it be of interest to others)? What thoughts have you had about it? What have you already tried, and where did you get stuck?
