β¦ Synopsis
Certain colored graphs are defined in terms of permutations in S, and the edge-chromatic automorphism groups of these graphs are studied. In fact, these groups are characterized in terms of the associated permutations. These groups are related to the groups of symmetries of certain drawings of cycles in the plane.

The concept of the star chromatic number of a graph was introduced by Vince (A. Vince, Star chromatic number, J. Graph Theory 12 (1988), 551--559), which is a natural generalization of the chromatic number of a graph. This paper calculates the star chromatic numbers of three infinite families of pla
## Abstract The vertex set of the reduced Kneser graph KG~2~(__m,2__) consists of all pairs {__a,b__} such that __a, b__Ξ΅{1,2,β¦,__m__} and 2β€|__a__β__b__|β€__m__β2. Two vertices are defined to be adjacent if they are disjoint. We prove that, if __m__β₯4 __and m__β 5, then the circular chromatic number
