Bicoloring Steiner triple systems
A Steiner triple system has a bicoloring with \(m\) color classes if the points are partitioned into \(m\) subsets and the three points in every block are contained in exactly two of the color classes. In this paper, the authors present necessary conditions for the existence of a bicoloring with three color classes and give a multiplication theorem for Steiner triple systems with three color classes. The authors also consider bicolorings with more than three color classes.
