We show that for each rational number r such that 4<r ≀ 5 there exist infinitely many cyclically 4-edge-connected cubic graphs of chromatic index 4 and girth at least 5-that is, snarks-whose flow number equals r. This answers a question posed by Pan and Zhu [Construction of graphs with given circula

We prove that there are effectively only finitely many real cubic number fields of a given class number with negative discriminants and ring of algebraic integers generated by an algebraic unit. As an example, we then determine all these cubic number fields of class number one. There are 42 of them.
