On a double triptych

I made a triptych that hangs on the living room wall. (If I get around to it, I may try to post a picture of it here.) It is a composite rendering of primitive plants on a black background that was inspired by a television show that I saw on prehistoric plants. Since I tend to be contrary, it is actually made up of six individual ceramic panels, rather than three panels. So, I guess that it really can’t be called a triptych.

Is it a di-triptych or a sextych?

Sextych sounds weird. That can’t be right. It’s too hard to pronounce.
