Query: Circular flow number of Goldberg snarks   A circular nowhere-zero $r$-flow on a bridgeless graph $G$ is an orientation
of the edges and an assignment of real values from $[1, r-1]$ to the edges in
such a way that the sum of incoming values equals the sum of outgoing values
for every vertex. The circular flow number of $G$ is the infimum over all
values $r$ such that $G$ admits a nowhere-zero $r$-flow. We prove that the
circular glow number of Goldberg snark $G_{2k+1}$ is $4+1/(k+1)$, proving a
conjecture of Goedgebeur, Mattiolo, and Mazzuoccolo.
