Abstract
We generalise the notions of good, middling good, and Verdier good morphisms of distinguished triangles in triangulated categories, first introduced by Neeman, to the setting of -angulated categories, introduced in Geiss, Keller, and Oppermann. We then prove that all morphisms of -angles in an -cluster tilting -angulated category are middling good for .
