Abstract

We characterize the switching classes that do not contain an acyclic graph. The characterization is by means of a set of forbidden induced subgraphs. We prove that in addition to switches of the cycles Cn for $n\geq 7$, there are only finitely many such graphs in 24 switching classes, all having at most 9 vertices. We give a representative of each of the 24 switching classes.
