The Circular Chromatic Index of Flower Snarks
View through CrossRef
We determine the circular chromatic index of flower snarks, by showing that $\chi'_c(F_{3})=7/2$, $\chi'_c(F_{5})=17/5$ and $\chi'_c(F_{k})=10/3$ for every odd integer $k\ge 7$, where $F_k$ denotes the flower snark on $4k$ vertices.
