WebAbstract. A cubic graph which is cyclically k -edge connected and has the further property that every edge belongs to some cyclic k -edge cut is called uniformly cyclically k -edge connected (U (k)). We classify the U (5) graphs and show that all cyclically 5-edge connected cubic graphs can be generated from a small finite set of U (5) graphs ...
