We use these to show that many of the triangulated quotients of $\Mod$ are not generated, as triangulated categories, by the corresponding quotient of $\mod$ considered as a full subcategory.5 pages, expanding on a construction from the author's PhD thesisRepresentation Theory16G60, 18A30, 18Exx, 18G25, 20C05, 20C20Finite dimensional modules and perpendicular subcategoriestext
