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

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
