More on the girth of graphs on Weyl groups

Samy A. Youssef, S. G. Hulsurkar (1993)

Archivum Mathematicum

Similarity:

The girth of graphs on Weyl groups, with no restriction on the associated root system, is determined. It is shown that the girth, when it is defined, is 3 except for at most four graphs for which it does not exceed 4.

Similarity:

If G is a minimally 3-connected graph and C is a double cover of the set of edges of G by irreducible walks, then |E(G)| ≥ 2| C| - 2.
