Jun 8, 2022 at 16:22 comment added Moishe Kohan @SelimG: From what I know, there are only finitely many explicitly known commensurabilify classes. If you find one example, you get infinitely many by taking unramified finite coverings.
Jun 8, 2022 at 12:46 comment added Selim G Thanks! Tretkoff's book is not open access, so I couldn't get much from these references unfortunately. It seems Hirzebruch in his original article builds only three such surfaces, do these methods yield more than that? Hopefully an infinity?
