## Abstract In this paper we describe almost all edge‐colored complete graphs that are fully symmetric with respect to colors and transitive on every set of edges of the same color. This generalizes the recent description of self‐complementary symmetric graphs by Peisert and gives examples of permu
It is shown that, for ⑀ ) 0 and n ) n ⑀ , any complete graph K on n vertices 0 ' Ž . whose edges are colored so that no vertex is incident with more than 1 y 1r 2 y ⑀ n edges of the same color contains a Hamilton cycle in which adjacent edges have distinct colors. Moreover, for every k between 3 and
## Abstract An edge‐colored graph __H__ is properly colored if no two adjacent edges of __H__ have the same color. In 1997, J. Bang‐Jensen and G. Gutin conjectured that an edge‐colored complete graph __G__ has a properly colored Hamilton path if and only if __G__ has a spanning subgraph consisting
