The least number of 3-cycles (cycles of length 3) that a hamiltonian tournament of order n can contain is n -2 (see [3]). Since each complete strongly connected digraph contains a spanning hamiltonian subtournament (see [2]), n-2 is also the least number of 3-cycles for these digraphs. In this pape

In this paper we present the upper and lower bounds of the longest directed cycle length for minimal strr,ng digraphs in terms of the numbers of vertices and arcs. These bounds are both sharp. In addition, we give analogous results for minimal 2-edge connected graphs.

Knuth proposed to compare his method and those of Luce for studying strongly connected digraphs. Changing Knuth's notation slightly we construct a set of strongly connected digraphs which is equal to the set of the compound circuits defined by Luce. (Let us recall that Luce proved that a minimal str

We say that a digraph D has the odd cycle property if there exists an edge subset S such that every cycle of D has an odd number of edges from S. We give necessary and sufficient conditions for a digraph to have the odd cycle property. We also consider the analogous problem for graphs.

A graph is called weakly triangulated if it contains no chordless cycle on five or more vertices (also called hole) and no complement of such a cycle (also called antihole). Equivalently, we can define weakly triangulated graphs as antihole-free graphs whose induced cycles are isomorphic either to C
