A linear forest is a graph that connected components are chordless paths. A linear partition of a graph G is a partition of its edge set into linear forests and la(G) is the minimum number of linear forests in a linear partition. It is well known that la(G) = 2 when G is a cubic graph and Wormald [17] conjectured that if |V (G)| ≡ 0 (mod 4), then it is always possible to find a linear partition in two isomorphic linear forests. We give here some new results concerning this conjecture.
