How many different planes pass through at least 3 vertices of a prism with regular pentagon bases?

I counted  42  different planes.

Also, since for example, the plane that goes through ABC also goes through the points  E  and  D, I called that plane ABCDE.

I named each plane by each vertex on the prism that it contains.

 

 

*edit* This could be wrong! I am not totally sure about it.
