  • Abstract
    We prove that the Petersen colouring conjecture implies a conjecture of Markstrِm saying that the line graph of every bridgeless cubic graph is decomposable into cycles of even length. In addition, we describe two infinite families of 4-regular graphs: the first family consists of 3-connected graphs with no even cycle decomposition and the second one consists of 4-connected signed graphs with no even cycle decomposition.
