Description
The Frobenius graph $\Gamma(G, H)$, for a proper subgroup $H$ of a finite group $G$, describes the constituents of the restrictions of the irreducible characters of $G$ to $H$. We investigate when this graph has diameter $3$.
This is joint work with L. Héthelyi, E. Horváth, and B. Külshammer.
