>>8506066I gave some thought, since Adamas and Lonsdaleite are two forms of diamond, I guess the idea here is to base their names on mineral formations?
So the VI- will always repeat if there is a carbon element in the molecule they are based the names on.
So XCIX-albere and C-efer probably total 99 and 100 if you count all the different atoms in the formation of that molecule. Just like a diamond is made of carbon (6).
