Impossible figures

I am sure everybody can see that the drawing (a) is an impossible figure. So I expect nobody will draw cubane like this; the correct drawing is (b).

cubane (wrong)
cubane (right)

In fact, if you pay attention, you will notice that the chemical databases are full of impossible figures. I just have corrected the drawing in ChEBI entry for codeinone (c). Next release, it will look like (d).
