本文给出了Frobenius群Z2n^2+2n+1×Z4的一类四度Frobenius图.沿用方、李和Praeger的方法,计算出了这一类图的直径和型(定理3.2).
As a part of the author's work of enumerating the edge-forwarding indices of Frobenius graphs, I give a class of valency four Frobenius graphs derived from the Frobenius groups Z2n^2+2n+1 × Z4. Following the method of X. G. Fang, C. H. Li and Praeger, some properties including the diameter and the type of this class of graphs are given(Theorem 2.2).
