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.
