So this question asks for which valus of n are Kn, Cn, Wn and Qn bipartite.
>>> are we supposed to consider n=0 or are these graphs only defined for n>0?--Tsnowdon 18:18, 1 November 2008 (UTC)
--- n>0, otherwise the graph would have no vertices. rtabchou
Are we supposed to consider n=1 for K1 as bipartite, or do we need at least 2 vertices for a bipartite graph?
