Bicolouring Steiner systems S(2,4,v)
Abstract
We discuss colourings of elements of Steiner systems S(2,4,v) in which the elements of each block get precisely two colours. We show that there exist systems admitting such colourings with arbitrary large number of colours, as well as systems which are uncolourable.
