Fan–Raspaud conjecture for bridgeless cubic graphs

From papers

Let GG be a bridgeless cubic graph. Fan–Raspaud conjecture. The graph GG contains three perfect matchings M1,M2,M3M_1,M_2,M_3 such that no edge is covered by all three of them. The Berge–Fulkerson conjecture implies this conjecture, but the Fan–Raspaud conjecture remains open, including in the finite setting discussed in the source.
