I don’t think so; $\star(e_1 \wedge e_2 \wedge e_2) = 1$, so $\star(3e_1 \wedge e_2 \wedge e_2) = 3$.

The halfedge mesh we introduced in lecture will in general encode complexes beyond oriented simplicial complexes—in particular, it will describe a 2-dimensional CW complex. If we limit each face to having three sides, then a halfedge mesh will encode a \(\Delta\)-complex. (See the notes above for definitions!)

Yes, thank you. I have fixed this typo for future years.
