Aldred–Labbate–Robertson–Seymour conjecture on cyclically 5-edge-connected odd 2-factored snarks

From papers

Let GG be a cyclically 55-edge-connected odd 22-factored snark, where a snark is a bridgeless cubic graph of chromatic index four and odd 2-factored means that every cycle in every 22-factor is odd. Let PP be the Petersen graph and J(t)J(t) the Flower snark. Aldred–Labbate–Robertson–Seymour's conjecture. The graph GG is either the Petersen graph or the Flower snark J(t)J(t) for odd t5t\geq5. This is a proposed partial characterization after earlier constructions produced counterexamples to the broader odd 22-factored snark conjecture.
