Typo in Ex. H.4.2

I believe that instead of the condition to prove being E=-\left|V\right|, it should be E=-\left|E\right| instead.

Hello @EmGiXIII, welcome to the forum!

Yes, I think you’re correct, which would make E an unfortunate choice of notation for the number of edges. I’ll think of how to fix it and will update it soon :slight_smile:

Thank you for spotting this, you have great attention to detail!
