Cyclically 5-edge-connected odd 2-factor classification conjecture

Let GG be a cyclically 55-edge-connected odd 22-factored snark, meaning that GG is a snark, every cycle in every 22-factor of GG is odd, and no edge cut of size at most four separates two components each containing a cycle. Let PP denote the Petersen graph and J(t)J(t) the Flower snark. Cyclically 5-edge-connected classification conjecture. If GG is a cyclically 55-edge-connected odd 22-factored snark, then GG is either the Petersen graph or the Flower snark J(t)J(t) for odd t5t\ge 5. This is a partial characterization problem for odd 22-factored snarks; the source gives no resolution of this proposed classification.
