Classification of 3-GNDB Graphs

Abstract: A nonempty graph G is called generalized 3-distance-balanced, (3-GDB) whenever for every edge ab, |Wab|=3|Wba| or conversely. As well as a graph G is called generalized 3-nicely distance-balanced (3-GNDB) whenever for every edge ab of G, there exists a positive integer g, such that: |Wba|=gG. In this paper, we classify 3-GNDB graphs with, gG \in{1,2}.
