✦ Synopsis
We show that the maximum size of a B 2 -sequence of binary n-vectors for large enough n is at most 2 0.5753n , thus improving on the previous bound 2 0.6n due to B. Lindstro m.

A harmonious coloring of a simple graph G is a proper vertex coloring such that each pair of colors appears together on at most one edge. The harmonious chromatic number h(G) is the least number of colors in such a coloring. We obtain a new upper bound for the harmonious chromatic number of general
## Abstract We consider the following question: how large does __n__ have to be to guarantee that in any two‐coloring of the edges of the complete graph __K__~__n,n__~ there is a monochromatic __K__~__k,k__~? In the late 1970s, Irving showed that it was sufficient, for __k__ large, that __n__ ≥ 2^_
## Abstract A cyclic coloring of a plane graph is a vertex coloring such that vertices incident with the same face have distinct colors. The minimum number of colors in a cyclic coloring of a graph is its cyclic chromatic number χ^__c__^. Let Δ^\*^ be the maximum face degree of a graph. There exist
