Hi, A cylinder has 3 faces - 2 circle ones and a rectangle (if you take the top and bottom off a tin can then cut the cylinder part on the seam and flatten it out you would get a rectangle). It has 2 edges and no vertices (no corners). Diane. Hi Stacy,
Every line graph of a 4-edge-connected graph is Z 3 -connected HongJian Lai â, Lianying Miao â , Yehong Shao â¡ AbstractWe prove that every line graph of a 4-edge-connected graph is Z 3 -connected.orexample, let G denote the loopless connected graph with two vertices and with 4 edges. With thetraditional deï¬nition of a line graph, the line graph of G will be a K 4, which is not Z 3 -connected.
