There's a first reflection point for each speaker on every wall plus on the floor and ceiling also.
The most important points to treat according to Floyd Toole in his new book "Sound Reproduction" are the front and back walls. He believes the reflections from the side walls enhance the sense of spaciousness and that most people prefer them untreated but he does state that some people, especially musicians, are sensitive to first reflection strength so treating the side wall first reflections is optional in his view.
In real life, many rooms have left/right asymmetries such as different distances between speaker and wall, and/or walls with surfaces of differing reflectivity such as plaster board for one wall and glass window area for the opposite wall. If there are asymmetries causing left/right imbalance in the sound stage and imaging, treating the side wall first reflection points will reduce/eliminate those problems but at the loss of the spaciousness effects that Toole refers to.
Some people are strong on treating the ceiling first reflections but I've left those alone in my room simply because I don't want to have to permanently mount treatments on my ceiling. Low ceilings would benefit most from treatment but they're also the ones that create physical problems because the treatment lowers the effective ceiling height even more.
Good carpet or thick rugs are sufficient for the floor first reflections.
