  Let G be a group. A subset X of G is a set of pairwise non-commuting elements
if xy is not equal to yx for any two distinct elements x and y in X. If
|X|>=|Y| for any other set of pairwise non-commuting elements Y in G, then X is
said to be a maximal subset of pairwise non-commuting elements. In this paper
we determine the cardinality of a maximal subset of pairwise non-commuting
elements for finite minimal non-abelian groups.
