... factors and β 1-factors. In [22, 34], the authors consider the pro blem of finding t he total number of triangles in 2-factorizations of K n . In [1, 23], the problem of finding the total number of ... 1-factors. In [11], Bryant considers the problem of finding decompositions of K n into 2- factors in which most of the 2-factors are Hamilton cycles and the r...
