# Graph Theory Notation Question

I'm not sure if this warrants a full post, but I am doing my homework and I came across notation I'm not familiar with. Skimming the chapter it's not in there either.

It says "Draw W6" but W6 has a bar over it, like complex conjugate. What does this mean? I know what W6 looks like.

Without seeing any context, my best guess is that $\overline{W_6}$ means the complement of $W_6$ -- everything in the graph that isn't in $W_6$. An image of the page might be helpful.
